JAVA基础:数组遍历

遍历：一个一个访问

 

package com.itheima.arry;

public class ArryDemo2 {
    public static void main(String[] args) {
        //掌握数组遍历
        int[] ages=new int[]{12,24,36};
//        System.out.println(ages[0]);
//        System.out.println(ages[1]);
//        System.out.println(ages[2]);


        for(int i=0;i<ages.length;i++){
            System.out.println(ages[i]);
        }
        //输入ages.fori回车即可快速进行数组遍历
        for (int i = 0; i < ages.length; i++) {
            
        }

    }
}

 

 

 

案例:

 

 

package com.itheima.arry;

public class ArrayDemo3 {
    public static void main(String[] args) {
        int[] money=new int[]{16,26,36,6,100};
        int all=0;
        for (int i = 0; i < money.length; i++) {
            all=all+money[i];
        }
        System.out.println(all);
    }
}
