Java 如何将数组与if-else语句一起使用？

我有以下代码：

 String[] sweetFlevors = { "Caramel", "Cinnamon", "Wetermelon", "Backed Beans" };

 String[] savoryFlavors = { "Sea Salt", "Potato Chip", "Carrot", "Barbque" };

 int[] numberRows = { 1, 2, 3, 4 };
 int[] numberCol = { 1, 2 };

 for (int col = 0; col < numberCol.length; col++) {
     System.out.println("       " + numberCol[0] + "         " + numberCol[1]);

     for (String sweet: sweetFlevors) {
         for (String savory: savoryFlavors) {

             for (int row = 0; row < numberRows.length; row++) {
                 System.out.print(numberRows[row] + ". ");

                 System.out.println(sweet + " and " + savory);
             }
         }
     }
 }

我不知道如何删除第二行列？为什么我会得到它

谢谢您的帮助：）

您正在打印列标题两次，因为您已将其放入

for

循环

for（int col=0；col

。你必须这样做：

    1         2
1. Caramel and Sea Salt
2. Caramel and Sea Salt
3. Caramel and Sea Salt
2. Wetermelon and Carrot
3. Backed Beans and Barbque
4. Backed Beans and Barbque
       1         2     //  How to delete this line?
1. Caramel and Sea Salt
2. Caramel and Sea Salt

String[] sweetFlevors = { "Caramel", "Cinnamon", "Wetermelon", "Backed Beans" };

String[] savoryFlavors = { "Sea Salt", "Potato Chip", "Carrot", "Barbque" };

int[] numberRows = { 1, 2, 3, 4 };
int[] numberCol = { 1, 2 };

System.out.println("       " + numberCol[0] + "         " + numberCol[1]);
for (int col = 0; col < numberCol.length; col++) {
    for (String sweet: sweetFlevors) {
        for (String savory: savoryFlavors) {
            for (int row = 0; row < numberRows.length; row++) {
                System.out.print(numberRows[row] + ". ");

                System.out.println(sweet + " and " + savory);
            }
        }
    }
}

String[]sweetFlevors={“焦糖”、“肉桂”、“湿玉米”、“背豆”}；
String[]savoryFlavors={“海盐”、“土豆片”、“胡萝卜”、“烤肉”}；
int[]numberRows={1,2,3,4}；
int[]numberCol={1,2}；
System.out.println（“+numberCol[0]+”+numberCol[1]）；
for（int col=0；col

你问什么真的不清楚。你应该解释你想做什么，得到什么，并请以可读的方式格式化你的代码。我必须练习数组，因此我做各种各样的代码练习。
