获取数组里面的内容并输出显示。

使用循环输出数组

public class Welcome {public static void main(String[] args){String[] runoobs = new String[3];runoobs[0] = "百度";runoobs[1] = "谷歌";runoobs[2] = "火狐";for (int i = 0; i < runoobs.length; i++){System.out.println(runoobs[i]);}}
}

结果输出

百度
谷歌
火狐

使用for语句输出

import java.lang.*;
public class Main{ public static void main(String args[]) {       String[] runoobs = new String[3];      runoobs[0] = "百度";      runoobs[1] = "谷歌";     runoobs[2] = "火狐";      for (String obj:runoobs){        System.out.println(obj+"\n");      }   }
}

使用迭代遍历打印元素

import java.util.*;
import java.lang.*;
public class Main {  public static void main(String args[]) {    ArrayList<String> runoobs = new ArrayList<String>();      runoobs.add("www.");       runoobs.add("baidu");    runoobs.add(".com");     for (Iterator<String> iterator = runoobs.iterator(); iterator.hasNext(); System.out.println(iterator.next())) { }    }
}
