How to break out of a loop in java

The difference between break, continue and return:

break: The default is to jump out of the innermost loop, also It is the nearest loop where break is located.

continue: Terminate this cycle and continue the next cycle.

return: End the current method.

Simple test of 3-layer loop:

for (int i = 0; i < 3; i++) {
    for1:
    for (int j = 0; j <3; j++) {
        for2:
            for (int m = 0; m < 3; m++) {
                for3:
                    System.out.println(i+"--"+j+"--"+m);
            }
        }
    }

The results are as follows:

0--0--0
0--0--1
0--0--2
0--1--0
0--1--1
0--1--2
0--2--0
0--2--1
0--2--2
1--0--0
1--0--1
1--0--2
1--1--0
1--1--1
1--1--2
1--2--0
1--2--1
1--2--2
2--0--0
2--0--1
2--0--2
2--1--0
2--1--1
2--1--2
2--2--0
2--2--1
2--2--2

Simple test break:

for (int i = 0; i < 3; i++) {
    for1:
    for (int j = 0; j <3; j++) {
        for2:
            for (int m = 0; m < 3; m++) {
                for3:
                    if (m == 1) {
                        break;
                    }
                    System.out.println(i+"--"+j+"--"+m);
            }
        }
    }

The results are as follows:

0--0--0
0--1--0
0--2--0
1--0--0
1--1--0
1--2--0
2--0--0
2--1--0
2--2--0

Simple test continue:

for (int i = 0; i < 3; i++) {
    for1:
    for (int j = 0; j <3; j++) {
        for2:
            for (int m = 0; m < 3; m++) {
                for3:
                    if (m == 1) {
                        continue;
                    }
                    System.out.println(i+"--"+j+"--"+m);
            }
        }
    }

The results are as follows:

0--0--0
0--0--2
0--1--0
0--1--2
0--2--0
0--2--2
1--0--0
1--0--2
1--1--0
1--1--2
1--2--0
1--2--2
2--0--0
2--0--2
2--1--0
2--1--2
2--2--0
2--2--2

Simple test return:

for (int i = 0; i < 3; i++) {
    for1:
    for (int j = 0; j <3; j++) {
        for2:
            for (int m = 0; m < 3; m++) {
                for3:
                    if (m == 1) {
                        return;
                    }
                    System.out.println(i+"--"+j+"--"+m);
            }
        }
    }

The results are as follows:

0--0--0
