java几个简单的循环

1.增强for循环

java5引入了主要用于数组的增强型for循环。

public class forEnhanced {    public static void main(String[] arys){        int[] numbers = {1,2,3,4,5};        for (int x : numbers){            System.out.println(x);        }        String[] names = {"Tome","Jone","liHua","xiaoMing","geGe"};        for (String x : names){            System.out.println(x);        }    }}

2.简单的for循环：

public class forDemo {    public static void main(String[] args){        for (int x=0;x<20;x++){            System.out.println("value of x:"+x);        }    }}
3.简单的while循环：
public class whileDemo {    public static void main(String[] arys){        int x = 10;        while (x<20){            System.out.println("value of x:" + x);            x++;        }    }}

4.java关键字continue
public class continueDemo {    public static void main(String[] args){        int[] numbers={1,2,3,4,5};        for (int x : numbers){            if (x == 3){            continue;            }            System.out.println("x:"+x);        }    }}

5.java关键字break:

public class breakDome {    public static void main(String[] arys){        int[] numbers = {1,2,3,4,5};        for (int x : numbers){            if (x == 3){                break;            }            System.out.println(x);        }    }}

结果对于大家来说肯定都知道是啥啦。如果有不知道答案的，直接拷贝运行即可。
