如何顯示在Java中數組的數組元素

Question

以下是我試圖

import java.lang.String.*; 
import java.io.*; 

public class Main { 
public static void main(String[] args) { 
String [][] array1 = new String[][] { 
    {"One"}, 
    {"One", "Two", "Three"}, 
    {"One"," Four"," Five"}, 
    {"One"," Four", "Six"," Seven"}, 
    {"Seven", "Eight"," One"}, 
    {"One"}, 
    {"One"," Nine"}, 
    {"One", "Nine"," Seven"}, 
    {"One"," Nine"} 
}; 
for (int row1=0;row1<=array1.length;row1++){ 
for (int cols=1 ;cols<array1[row1].length ;cols++){ 
System.out.println(array1[0][0] +" "+ array1[row1][cols]); 
} 
} 
} 
} 

我想作爲

One 
One Two 
One Three 
One Four 
One Five 
One Four 
One Six 
One Seven 
Seven Eight 
Seven One 
One 
One Nine and so on till the end of the array. 

顯示元素的代碼的輸出是：

One Two 
One Three 
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 9 
One Four 
One Five 
One Four 
     at javaapplication12.Main.main(Main.java:45) 
One Six 
One Seven 
One Eight 
One One 
One Nine 
One Nine 
One Seven 
One Nine 
Java Result: 1 
BUILD SUCCESSFUL (total time: 0 seconds) 

請建議我該怎麼做才能獲得優先輸出..任何幫助將不勝感激...

試試下面的代碼

for (String[] tmpArray: array1) { 
     if(tmpArray.length == 1) 
     { 
      System.out.println(tmpArray[0]); 
      continue; 
     } 
     for (int i = 1; i < tmpArray.length; i++) { 
      System.out.println(tmpArray[0] + " " + tmpArray[i]); 
     } 
    }
