The Java file on this page 
represents a complete source 
file. Your job is to play JVM 
and determine what would be 
the output when the 
program runs?
Exercise

class Output {
public static void main(String [] args) {
Output o = new Output();
o.go();
}
void go() {
int y = 7;
for(int x = 1; x < 8; x++) {
y++;
if (x > 4) {
System.out.print(++y + “ “);
}
if (y > 14) {
System.out.println(“ x = “ + x);
break;
}
}

A working Java program is all scrambled up on the fridge. Can you 
reconstruct the code snippets to make a working Java program that 
produces the output listed below? Some of the curly braces fell on the 
floor and they were too small to pick up, so feel free to add as many of 
those as you need!

System.out.println(x + “ “ + y);
