break

• 强制退出循环，不终止程序

package com.tiepi;

public class Loop {
    public static void main(String[] args) {
        int i = 0;
        while (1<100){
            i++;
            System.out.println(i);
            if (i == 30){
                break;
            }
        }
        System.out.println("Hi");
    }
}

continue

• 用于终止某次循环过程

package com.tiepi;

public class Loop {
    public static void main(String[] args) {
        int i = 0;
        while (i<100){
            i++;
            if (i%10 == 0){
                System.out.println();
                continue;
            }
            System.out.print(i+"\t");
        }
    }
}
