第二十讲—— Break 与continue

第二十讲—— Break 与continue

break

break用于强制退出循环,但是不会停止程序

package scanner;

public class Demo05 {
    public static void main(String[]args){
        int i = 0;
        while(i<10){
            i++;
            System.out.println(i);
            if(i==5){
                break;
            }
        }
        System.out.println("Hello World!!!");
    }
}

continue

continue用于循环语句中,用于终止某次循环过程,从头开始

package scanner;

public class Demo05 {
    public static void main(String[]ages){
        int i = 0;
        while(i<10){
            i++;
            System.out.println(i);
            if(i==5){
                continue;
              

            }
        }
        System.out.println("Hello World!!!");
    }
}
