Thread: Help with Looping out of a user saying the word NEW in the console

I need to know how to make my code repeat if the user types in NEW at the end of the program. Anybody know how? Please it is for a class

Code:




import java.util.Scanner;



public class Calc {


static Scanner trap = new Scanner (System.in);

public static void main( String args []) throws InterruptedException
{
//Variables: Base 1, Base 2, Height //



double B1;
double B2;
double height;


System.out.println("What is the length of the top of your trapezoid?");
B1 = trap.nextDouble();

System.out.println("What is the length of the bottom of your trapezoid? ");
B2 = trap.nextDouble();

System.out.println("What is the height of your trapezoid?");
height = trap.nextDouble();

double b3 = B1 + B2;

double almArea = b3 / 2;

double area = almArea * height;

System.out.println("The area of your trapezoid is:" + area);

Thread.sleep(2000);

System.out.println("Would you like to use me again? Type NEW if yes.");



}








}

you could make a boolean and use a while loop

and you need to

System.out.println("Would you like to use me again? Type NEW if yes.");
//do something here to accept the users input to know what they typed and what do they do if they dont want to use it again? and why not type yes if yes(just curious)?

Could you please explain to me how I would do that?

booleans are true or false

boolean rerun = true;

then put your code you would like to restart inside a while loop...here is how to use a while loop
The while and do-while Statements (The Java™ Tutorials > Learning the Java Language > Language Basics)

you could use the do while loop also

Not quite understanding the while loop thing. Any chance you can write it for me in the code, so I can understand its realation to my code?

Thanks man

Try this to improve your understanding. Applying your understanding to your code is your task, not someone else's.

Yes, mate. But after reading that I still am not sure how I can get this to work in my program.

this is a while loop

while (insert a boolean here) {
/*this is where you put all the code you want to loop while the boolean is true
when all this code is executed it checks to see if the boolean is true still and if it is it executes the code here again until the boolean is false*/
}

}

Thanks mate I got it to work!
