Thread: Java loop help

Hi I need help with this java code, I need the program to run until user enters -1 instead of 0 or 1

[code]
public static void main(String args[])
{
Scanner input = new Scanner(System.in); //New scanner for input

System.out.println("Ange längde på de 2 lika långa sidorna (Avsluta med -1)");
int length = input.nextInt(); //variable length with the users input

System.out.println("Ska de räta vinkeln vara nedåt (0) eller uppåt (1)");
int side = input.nextInt();


if(side == 0) // if user enter 0 this loop is running
for(int i = 1; i<=length; i++)

{
for(int j = 1; j<=i; j++){
System.out.print("*");

}
System.out.println();
}


if(side == 1) // if user enter 1 this loop is running
for(int i = length; i>=0; i--)
{
for(int j = 0; j<i; j++){
System.out.print("*"); // prints * on the same line depends on loop

}
System.out.println(); // new line
}

}// end main

[code]

do {

// Code

// if (input == 1)
// end = true;

}
while (!end);

Very simple do while loop, use it to achieve your desired result.
