二维字符串数组在Java [英] Two dimensional string array in java

问题描述

我是新来的Java，请帮助我这个问题。结果
我有一个字符串可以说

I am new to java please help me with this issue.
I have a string lets say

adc|def|efg||hij|lmn|opq

我现在拆分此字符串，并使用它存储在一个数组

now i split this string and store it in an array using

String output[] = stringname.split("||");

现在我又需要基于对拆分|
我需要这样的东西。

now i again need to split that based on '|' and i need something like

改编[1] [] = ADC，编曲[2] [] =高清结果等等，这样我可以访问每一个元素。
就像一个二维字符串数组。
听说这个可以用的ArrayList 来完成，但我无法弄清楚。
请帮助。

arr[1][]=adc,arr[2][]=def
and so on so that i can access each and every element. something like a 2 dimensional string array. I heard this could be done using Arraylist, but i am not able to figure it out. Please help.

推荐答案

下面是除了名的解决方案[0] [0] =ADC，名字[0] [1] =高清等等：

Here is your solution except names[0][0]="adc", names[0][1]="def" and so on:

String str = "adc|def|efg||hij|lmn|opq";
String[] obj = str.split("\\|\\|");
    int i=0;
    String[][] names = new String[obj.length][]; 

    for(String temp:obj){
        names[i++]=temp.split("\\|");

    }
List<String[]> yourList = Arrays.asList(names);// yourList will be 2D arraylist.
System.out.println(yourList.get(0)[0]); // This will print adc.
System.out.println(yourList.get(0)[1]); // This will print def.
System.out.println(yourList.get(0)[2]); // This will print efg.
               // Similarly you can fetch other elements by yourList.get(1)[index]
