我如何在Java中將String []轉換爲String [] []？

Question

如何將一個String []數組轉換爲String [] []？例如，如果String []如下所示：String [] array = new String [] {「Artist，Song，Genre」};如何將其轉換爲String [] []，以便「Artist」位於一個「單元格」中，例如String [0] [0] =「Artist」;

謝謝。

Answer 1

試試這個：

String[] array = new String[]{"a,b,c", "1,2,3", "x,y,z"}; 

String[][] twoDim = new String[array.length][]; 

for (int i = 0; i < twoDim.length; i++) 
    twoDim[i] = array[i].split(","); 

System.out.println(Arrays.deepToString(twoDim)); 

打印：

[[a, b, c], [1, 2, 3], [x, y, z]]

或者，也許這是後你是什麼：

String[][] twoDim = { { "Artist1", "Song1", "Genre1" }, 
         { "Artist2", "Song2", "Genre2" }, 
         { "Artist3", "Song3", "Genre3" } }; 

Answer 2

你的意思是這樣的：

String[][] array = new String[][] { 
    new String[] { 
     "Artist", "Genre", "Song" 
    }, 
    new String[] { 
     "artist1", "genre1", "song1" 
    }, 
    new String[] { 
     "artist2", "genre2", "song2" 
    } 
};
