Usage analysis of break and continue

Introduction to the usage of break and continue:

(recommended learning: java entry program)

break

1. Break is used in a switch statement to terminate the switch statement;

2. When break is used in a loop, it jumps out of the loop;

(1) break is used In the switch statement, terminate the switch statement

Example:

int a=4;
        switch(a){
            case 1:
                System.out.println("星期一");
            case 2:
                System.out.println("星期二");
            case 3:
                System.out.println("星期三");
            case 4:
                System.out.println("星期四");
                break;
            case 5:
                System.out.println("星期五");
            case 6:
                System.out.println("星期六");
            case 7:
                System.out.println("星期日");
            default:
                System.out.println("你输入的有误");
        }

Execution result:

(2) break When used in loops, jump out of the loop

Example:

        int sum=0;
        for(int i=1;i<=100;i++){
            if(i>10)
                break;
            sum+=i;
        }

Execution result:

continue

continue is used in a loop to jump out of this loop and continue to execute the next loop;

Example:

int i;
        for(i=1;i<10;i++){
            if(i==5)
                continue;
            System.out.print(i+"  ");
        }

Execution result:

You can see that when i=5, the continue key is encountered word, jump out of this loop, and continue to execute the loop after i=6.
