break语句存在于当前循环控制结构中，并跳转到它后面，而continue语句也退出，但跳转回循环条件。

答得好，简单准确。

我会添加一个代码示例。

C:\oreyes\samples\java\breakcontinue>type BreakContinue.java

    class BreakContinue {

        public static void main( String [] args ) {

               for( int i = 0 ; i < 10 ; i++ ) {

                     if( i % 2 == 0) { // if pair, will jump
                         continue; // don't go to "System.out.print" below.
                     }

                     System.out.println("The number is " + i );

                     if( i == 7 ) {
                         break; // will end the execution, 8,9 wont be processed
                      }

               }
        }

    }

C:\oreyes\samples\java\breakcontinue>java BreakContinue
The number is 1
The number is 3
The number is 5
The number is 7

Break只留下一个循环，继续跳转到下一个迭代。

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

简单的程序，了解继续和中断之间的区别

当使用continue时

    public static void main(String[] args) {
    System.out.println("HelloWorld");
    for (int i = 0; i < 5; i++){
        System.out.println("Start For loop i = " + i);
        if(i==2){
            System.out.println("Inside if Statement for i = "+i);
           continue;
        }
        System.out.println("End For loop i = " + i);
    }
    System.out.println("Completely out of For loop");
}


OutPut:
HelloWorld
Start For loop i = 0
End For loop i = 0
Start For loop i = 1
End For loop i = 1
Start For loop i = 2
Inside if Statement for i = 2
Start For loop i = 3
End For loop i = 3
Start For loop i = 4
End For loop i = 4
Completely out of For loop

什么时候使用break

public static void main(String[] args) {
    System.out.println("HelloWorld");
    for (int i = 0; i < 5; i++){
        System.out.println("Start For loop i = " + i);
        if(i==2){
            System.out.println("Inside if Statement for i = "+i);
           break;
        }
        System.out.println("End For loop i = " + i);
    }
    System.out.println("Completely out of For loop");
}

Output:
HelloWorld
Start For loop i = 0
End For loop i = 0
Start For loop i = 1
End For loop i = 1
Start For loop i = 2
Inside if Statement for i = 2
Completely out of For loop

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。
