java学习笔记（七）：for循环

java的for循环和c++的for循环类似

 public class Test {
    public static void main(String args[]) {
       for(int x = 10; x < 20; x = x+1) {
          System.out.print("value of x : " + x );
          System.out.print("\n");
       }
    }
 }

运行输出：

value of x : 10
value of x : 11
value of x : 12
value of x : 13
value of x : 14
value of x : 15
value of x : 16
value of x : 17
value of x : 18
value of x : 19

Java 引入了一种主要用于数组的增强型 for 循环。

 public class Puppy{
     public static void main(String[] args){
         int[] Nums = {10,20,30,40,50,60};
         for(int x : Nums){
             System.out.print(x);
             System.out.print(",");
         }

         System.out.println();
         String[] Names = {"Jacky","Tom","Lily"};
         for(String name : Names){
             System.out.print(name);
             System.out.print(',');
         }
     }
 }

运行输出：

10,20,30,40,50,60,
Jacky,Tom,Lily,
