Print Initial Age with airSlate SignNow

Print initial age

all right hello everyone um so this is going to be the first of many videos on the programming challenges in the book starting out with Java by Tony Cadiz so basically after every chapter there are a couple of programming challenges you know after that chapter and that focus it focuses on just that chapter and this is the first of the programming challenges in Chapter one and I'll be doing them one after yet one or the other and I'll be using dr. Java to create the programs and I'll list the questions in this forming comment right here alright so I'm not gonna waste too much time I'm just gonna head straight into the first question it's a name age and uh non-income so basically this program wants us to create a couple of variables a strength to hold a name and integer to hold an age a double to hold the animal payoffs of a person of someone and it wants us to display the details in this form so my name is Joe Mahoney in this form so I'm mr. Khan I'm not gonna waste too much time but before I start I'd like to mention out that this is not going to be a teaching Java course I'm not only I'm not going to teach the whole Java course um it's just going to be trying to solve the program's at the end of the chapter just trying to solve them I'm assuming that at least you know the basics of java the programs are only focused on you know it's chapter by chapter if you only talked about all the only about the chapters in the book so this is only about things in Chapter one so I'm expecting that at least you you know the you know you know the basics of of Java the variables numbers you know things like that so we're only trying to solve the problem all right so I'm just gonna head straight to this and the first thing we're gonna do was to declare a string a string my typing is not the best though might happen is not the best so I'll try my best to to to catch up we're going to declare a string and call it name and that's going to store the name of you know the person in this case Joe Mahoney and then the next thing we're going to do is declare an int we're gonna call it age that's gonna hold the age of it Joe Mahoney the third thing is a double that's going to hold animal pain let me just comment these out so that it's good practice the comments the program's out so I'm just gonna say Claire something very simple it's not the best okay so we need to store values in these variables now we have a name agent and okay so we're going to store the name Joe Mahoney in the string variable name so Jill and then store his age in the variable age in this case 26 it we don't have to put quotes around it because it's an integer and then the adult pay will be a hundred thousand oh all right so I made I made a mistake here I'm supposed to create a class and then I'm supposed to create a class you know basically for the program I was um I was I was you know speeding ahead ahead of myself all right so I'll just do that I just do it I'll just cut this and started so before we start we need a class obviously so public class I'm going to call this program name age income space so public class name age income we're going to create a the main method public static void main all right so again I'm expecting that you know the basics of this you know how to create it so I just put the program that what we just did inside so this is basically we need to put you know our code in the class it's in this case name age income all right so we have the variables now what the program wants us to do is to display these values in this form my name is Jill Mahoney my age is 26 and I hope to earn hundred thousand dollars per year so we have the values already stored in this so all we have to do is just print it out so first let me comment this out and say declare variables and then over here I'll just say print out details okay so all we have to do is just print it out so we do device system that out print and then we're gonna say my name yes we don't have to type Joe Mahoney because we have about the value already stored in the string variable name so we're going to concatenate it with a plus sign and put name because it contains their name Joe Mahoney and then concatenate it again with another string you know continue the string so basically what we have now is my name is Joe Mahoney we need to put a comma here my age yes we already have the value stored in H so we have to put all we all we need to do is just put age here and then we concatenate that again with another strength is we continuing it so we have my name is Joe Mahoney my age is 26 and I hope alright so this is where this is where the book has covered so far we're just going to write code based on what the book is booked us covered so far so in Chapter one it doesn't it doesn't it hasn't talked about how to convert you know numbers to you know to dollar values and all now I hope you get me but we're just going to put a dollar sign here so it appears in front of the number that is stored in the variable I know pain I'm going to concatenate it with per year all right so we're basically done with the program so I'm going to go ahead and compile it and we need to create a folder install the program in there so what I'm going to do is I'm going to try keep a folder of all these programs I'm going to create a folder on the desktop one second and then I'll name it I'll quit yet another folder in it now call it programming challenges create another folder and I'll call it chapter 2 yet another one and I'll call that name age income just remember that whatever name you give you a file name should match the name that you gave to your class so in this case I'm referring to this one this name it has to be the same as the name that you save the Java file so this is going to be a Java file named age income to Java I'm going to save it in this folder and basically it compiled you know well it didn't give us any errors so I'm going to go ahead and run it and we get an output which is my name is Joe Mahoney my name is 26 and I hope to earn 100,000 per year the only problem is it's not displaying exactly the way the program wants us to I mean the question is asking us to so as you can see that there's a line break here so need a line break here and the way you do that is we put an escape character and a new line break so basically it's an escape it's a new line character both together is a new line character because of this is called an escape character and the letter n we don't need a space here because there's no I'm sorry supposed to put this here right in front of I so that right after end it breaks it and then you know let me just save it so you can see what I'm talking about so I'll compile it again and run it yeah so it works so basically what what happened is this newline character breaks this whole statement this whole sentence breaks it into two and then puts I hope to earn on the next one it's a newline character if you put a space there it's gonna put a space right in front of I we don't need it we don't need any space here so just gonna go ahead and blow that space compile it and run it again so basically that's it I'm sorry the video was a bit rough but I but you get the idea hopefully as we move forward as I move forward to make them other programs that it becomes a bit smooth but basically is how you go about it program is done if you have any questions please comment down below and I'll do my best to answer you if you have any concerns about the whole program the whole program the whole interface about dr. Java how to you how to get it you just just let me know in the comments with any concerns and I'll try to address them so thank you very much for watching and I'll see you next time with the next program
