首先，我认为你应该知道在Java中有两种类型的中断和继续，即有标记的中断，无标记的中断，有标记的继续和无标记的继续。现在，我将谈谈它们之间的区别。

class BreakDemo {
public static void main(String[] args) {

    int[] arrayOfInts = 
        { 32, 87, 3, 589,
          12, 1076, 2000,
          8, 622, 127 };
    int searchfor = 12;

    int i;
    boolean foundIt = false;

    for (i = 0; i < arrayOfInts.length; i++) {
        if (arrayOfInts[i] == searchfor) {
            foundIt = true;
            break;//this is an unlabeled break,an unlabeled break statement terminates the innermost switch,for,while,do-while statement.
        }
    }

    if (foundIt) {
        System.out.println("Found " + searchfor + " at index " + i);
    } else {
        System.out.println(searchfor + " not in the array");
    }
}

未标记的break语句终止最里面的开关、for、while、do-while语句。

public class BreakWithLabelDemo {
public static void main(String[] args) {
    search:
    for (int i = 0; i < 3; i++) {
        for (int j = 0; j < 5; j++) {
            System.out.println(i + " - " + j);
            if (j == 3)
                break search;//this is an labeled break.To notice the lab which is search.
        }
    }
}

带标记的break终止外部语句。如果你javac和Java这个演示，你会得到:

0 - 0
0 - 1
0 - 2
0 - 3

class ContinueDemo {
public static void main(String[] args) {

    String searchMe = "peter piper picked a " + "peck of pickled peppers";
    int max = searchMe.length();
    int numPs = 0;

    for (int i = 0; i < max; i++) {
        // interested only in p's
        if (searchMe.charAt(i) != 'p')
            continue;//this is an unlabeled continue.

        // process p's
        numPs++;
    }
    System.out.println("Found " + numPs + " p's in the string.");
}

未标记的continue语句将跳过for、while、do-while语句的当前迭代。

public class ContinueWithLabelDemo {
public static void main(String[] args) {
    search:
    for (int i = 0; i < 3; i++) {
        for (int j = 0; j < 5; j++) {
            System.out.println(i + " - " + j);
            if (j == 3)
                continue search;//this is an labeled continue.Notice the lab which is search
        }
    }
}

一个带标签的continue语句将跳过当前使用给定标签标记的外部循环的迭代，如果你javac和java演示，你将得到:

0 - 0
0 - 1
0 - 2
0 - 3
1 - 0
1 - 1
1 - 2
1 - 3
2 - 0
2 - 1
2 - 2
2 - 3

如果你有任何问题，你可以看看这个Java教程:在这里输入链接描述

下面是break的语义:

int[] a = new int[] { 1, 3, 4, 6, 7, 9, 10 };
// find 9
for(int i = 0; i < a.Length; i++)
{
    if (a[i] == 9) 
        goto goBreak;

    Console.WriteLine(a[i].ToString());      
}
goBreak:;

下面是continue的语义:

int[] a = new int[] { 1, 3, 4, 6, 7, 9, 10 };
// skip all odds
for(int i = 0; i < a.Length; i++)
{
    if (a[i] % 2 == 1) 
        goto goContinue;

    Console.WriteLine(a[i].ToString());      

goContinue:;
}

继续声明停止滴定，开始下一次滴定 例:

System.out.println("continue when i is 2:");
    for (int i = 1; i <= 3; i++) {
        if (i == 2) {
            System.out.print("[continue]");
            continue;
        }
        System.out.print("[i:" + i + "]");
    }

和Break语句停止循环或退出循环

简单的例子:

Break离开了循环。

int m = 0;
for(int n = 0; n < 5; ++n){
  if(n == 2){
    break;
  }
  m++;
}

System.out.printl("m:"+m); // m:2

Continue将返回开始循环。

int m = 0;
for(int n = 0; n < 5; ++n){
  if(n == 2){
    continue; // Go back to start and dont execute m++
  }
  m++;
}

System.out.printl("m:"+m); // m:4

简单地说:break将终止当前循环，并在循环结束后的第一行继续执行。Continue跳转回循环条件并继续运行循环。

break语句跳出循环(要执行的下一个语句是右大括号之后的第一个语句)，而continue语句在下一个迭代中开始循环。
