How to jump out or terminate if statement in java

1. break

break: Break out of the current loop; but if it is a nested loop, you can only break out of the current layer of loops, and only break layer by layer can Break out of all loops.

for (int i = 0; i < 10; i++) {  
            if (i == 6) { 
                break;  
               // 在执行i==6时强制终止循环，i==6不会被执行  
                }
            System.out.println(i);  
        }  
  
  
输出结果为0 1 2 3 4 5 ；6以后的都不会输出

2. continue

continue: Terminate the current loop, but do not jump out of the loop (the statements after continue in the loop will not be executed), and continue to execute the loop according to the loop conditions.

for (int i = 0; i < 10; i++) {  
    if (i == 6)  {
        continue;  
      // i==6不会被执行，而是被中断了    
       } 
       System.out.println(i);  
   }
   
   输出结果为0 1 2 3 4 5 7 8 9；只有6没有输出

3. return

(1)return Exits from the current method, returns to the statement of the called method, and continues execution.

(2)return Returns a value to the statement that calls the method. The data type of the return value must be consistent with the type of the return value in the method declaration.

(3) Return can also be followed by no parameters. Without parameters, it returns empty. In fact, the main purpose is to interrupt the execution of the function and return to the calling function.

Special note: Methods with a return value of void must use return to jump out from a certain judgment.
