将一维数组存到二维数组 、将一维数组存到列表

public class Test0202 {

    public static void main(String[] args) throws ParseException {
      
        //将一维数组加入到二维数组
        //二维数组
        String arr[][] =  new String[3][]; 
        //一维数组
        String name[] = {"zs","ls","ww"};
        String nick[] = {"z1","l2","w3"};
        String pass[] = {"a123","l123","w123"};
        arr[0]=name;
        arr[1]=nick;
        arr[2]=pass;
        //遍历
        for(String x1[]:arr) {        
            for(String x:x1) {
                System.out.print(x+"\t");
            }
            System.out.println();
            
        }
    }

}

结果

zs    ls    ww    
z1    l2    w3    
a123    l123    w123

 

将一维数组存到列表

    //一维数组
        String name[] = {"zs","ls","ww"};
        String nick[] = {"z1","l2","w3"};
        String pass[] = {"a123","l123","w123"};
        
        List<String[]> array= new ArrayList<String[]>();
        array.add(name);
        array.add(nick);
        array.add(pass);
        
        for(String x1[]:array) {        
            for(String x:x1) {
                System.out.print(x+"\t");
            }
            System.out.println();
            
        }

结果：

zs    ls    ww    
z1    l2    w3    
a123    l123    w123
