### Java quiz 27: Multiple variables in a loop

Level: Normal

What is the output of the following code?

public class MyLoop
{
public static void main(String args[])
{
int x;
int y;
for(x = 0, y = 3; x < y; x += 2, y++)
{
System.out.print("");
}
System.out.print(x + "," + y);
}
}

1. The statement for(x = 0, y = 3; x < y; x += 2, y++) indicates that the initial value of x = 0 and y = 3. As long as x is smaller than y the body of the loop is executed.
2. x is smaller than y therefore, the body of the loop is exectued, the value of x is equal to x = x + 2 = 2, y = y + 1 = 3 + 1 = 4.
3. By the next exectuion the value of x = x + 2 = 2 + 2 = 4, and y = y + 1 = 4 + 1 = 5.
4. By the next execution the value of x = x + 2 = 4 + 2 = 6, and y = y + 1 = 5 + 1 = 6.
5. Now, the the execution of the loop is terminated because y is no longer greater than x.
