java - 打印二维字符串

Question

这个问题已经有答案了:

2D Array, output is no where near correct (2 个回答)

Java arrays printing out weird numbers and text [duplicate] (10 个回答)

已关闭 9 年前。

我定义了一个二维字符串对象，然后尝试打印它，但没有打印该字符串。有人可以告诉我我在这里缺少什么吗？

String[][] input = { { "a", "b", "c"}, { "a", "b", "a"} };

System.out.println(输入);

输出:

[[Ljava.lang.String;@6475d174

您还没有完全理解数组方面的问题...

int rowIndex, colIndex;
String[][] input = { { "a", "b", "c" }, { "a", "b", "a" } };
System.out.println(input[rowIndex][colIndex]);

//If you want to traverse through the entire 2-D array 
//all you will need to do is use two for loops
