1. for(int name:nameArray){}

2. for(){}

3. while{}

4. do{}while{}

public class Loop{  public static void main(String[] args){     int[] numList = {1,2,3,4,5,6,7,8,9,10};     //1.打印数组numList所有值     for(int i : numList){        System.out.print(i + " ");     }          System.out.println();     //2.打印数组numList的偶数     for(int i=0;i<numList.length;i++){        if(numList[i] % 2 ==0)            System.out.print(numList[i] + " ");     }     System.out.println();      //3.打印数组numList的奇数     int i = 0;     while(i < numList.length){        if(numList[i] % 2 != 0){           System.out.print(numList[i] + " ");                  }        i++;     }     System.out.println();     //4.累加     i = 0;     int sum = 0;     do{        sum += numList[i];               i++;     } while(i < numList.length);     System.out.print(sum);  }}

运行结果如下：

E:\java>javac Loop.java
E:\java>java Loop
1 2 3 4 5 6 7 8 9 10
2 4 6 8 10
1 3 5 7 9
