Java-break Jump Statement

When you develop code, you often wonder: How does a break jump-out statement apply?

There are two scenarios for using break: One, the switch statement. Second, the circular statement.

The switch statement is not introduced here, mainly the application of break in the loop.

 for (int i=0; i<5; i++) {    if(i = = 0) {    System.out.println (i)    ;　　  Break ;    }}

SYSTEM.OUT.PRINTLN ("Break Test");

This code indicates that when i=0, the output 0,break statement exits the loop directly.

The result is:

0 BreakTest

The above is in a single cycle of the application scenario, we will also encounter multiple loops when the situation, then break will jump out of which loop?

 for (int j=0; j<5; j + +) {    for (int i=0; i<5; i++) {    　　if( i = = 0) {        System.out.println (i)        ;　　  Break ;//(1)    }    }    System.out.println ("Jump out of Layer 1 for loop here");     if (j = = 0) {    System.out.println ("Terminator");    　　  Break ; //(2)    }}

This is a double-loop example, (1) where break jumps out of the inner Loop, (2) at the break out of the outer loop. In other words, break can only jump out of a 1-layer loop. This example uses two break to jump out of a double loop, and if only 1 break how do I skip to the outermost loop? Look at the following code:

First:for (int j=0; j<5; j + +) {    Second:for (int i=0; i<5; i++ {        if(i = = 0) {            System.out.println (i);              Break First ;        }    }    System.out.println ("Jump out of Layer 1 for loop here");     if (j = = 0) {        System.out.println ("Terminator");          Break ;    }}

Here I just need to give each cycle a name, so that you can jump to which loop you want him to jump to.

See here you learned the break statement?
