1、break使用会跳出（终止）当前循环：
package javaPrimary;
public class Loop {
public static void main(String[] args) {
for(int i=0; i<10; i++){
if(i==5){
break;
}
System.out.println(i);
}
}
}
输出：0 1 2 3 4
2、continue使用跳出当前循环，开使下一循环：
package javaPrimary;
public class Loop {
public static void main(String[] args) {
for (int i = 0; i < 8; i++) {
if (i == 5) {
continue;
}
System.out.println(i);
}
}
}
3、跳出多重循环：
package javaPrimary;
public class Loop {
public static void main(String[] args) {
loop: for (int i = 0; i < 10; i++) {
for (int j = 0; j < 10; j++) {
for (int k = 0; k < 10; k++) {
for (int h = 0; h < 10; h++) {
if (h == 6) {
break loop;
}
System.out.print(h);
}
}
}
}
System.out.println(" breakout");
}
}
