System.out.println("\nLooping with No Break:");
for (int x = 0; x < 3; x++){ //outer loop (x loop)
for (int y = 0; y < 3; y++){ //inner for loop (y loop)
System.out.println("x = " + x + " and y = " + y);
}
}
6.
Now add the second nested
for
loop section. This will include a
break
statement, which is exe-
cuted whenever
x
and
y
have the same value. Type the second nested
for
loop as follows:
System.out.println("\nBreak with No Label:");
for (int x = 0; x < 3; x++){//outer loop (x loop)
for (int y = 0; y < 3; y++){ //inner loop (y loop)
System.out.println("x = " + x + " and y = " + y);
if (x == y) { //new conditional expression
System.out.println("Break out of y loop.\n");
break; //new break statement
}
}
}
7.
Finally, add a third nested
for
loop section. This time, include both a
break
statement and a label.
It will be executed under the same condition as the previous section. Type the third nested
for
loop
as follows:
System.out.println("\nBreak with No Label:");
outer: // new label
for (int x = 0; x < 3; x++) {// outer loop (x loop)
for (int y = 0; y < 3; y++) { // inner loop (y loop)
System.out.println("x = " + x + " and y = " + y);
if (x == y) { // same conditional expression
System.out.println("Break out of both loops.\n");
break outer; // new break statement with label
}
}
}
8.
All of the preceding
for
loops should be between the
{}
of the
main
method. Your class body
should now look like this:
public class BreakLoop {
public static void main(String[] args) {
System.out.println("\nLooping with No Break:");
for (int x = 0; x < 3; x++) { // outer loop (x loop)
for (int y = 0; y < 3; y++) { // inner for loop (y loop)
System.out.println("x = " + x + " and y = " + y);
}
}
System.out.println("\nBreak with No Label:");
for (int x = 0; x < 3; x++) {// outer loop (x loop)
for (int y = 0; y < 3; y++) { // inner loop (y loop)
System.out.println("x = " + x + " and y = " + y);
if (x == y) { // new conditional expression
