如何将foreach c#2d数组循环转换为java

本文关键字:循环 转换 java 数组 c#2d foreach | 更新日期: 2023-09-27 18:05:43

我有一段C#代码,需要用java重写。

private static void ShowGrid(CellCondition[,] currentCondition)
{
        int x = 0;
        int rowLength =5;
        foreach (var condition in currentCondition)
        {
            var output = condition == CellCondition.Alive ? "O" : "·";
            Console.Write(output);
            x++;
           if (x >= rowLength)
            {
                x = 0;
                Console.WriteLine();
            }
        }
}

到目前为止,我的java代码如下:

private static void ShowGrid(CellCondition[][] currentCondition) {
        int x = 0;
        int rowLength = 5;
        for(int i=0;i<currentCondition.length;i++){
            for(int j =0; j<currentCondition[0].length;j++){
                CellCondition[][] condition = currentCondition[i][j];
                //I am stuck at here
                x++;
            if(x>=rowLength){
               x=0; 
               System.out.println();
               }
            }
        }
}

我被困在CellCondition[][] condition = currentCondition[i][j];行之后,我也不确定循环是否正确。任何建议都将不胜感激。

如何将foreach c#2d数组循环转换为java

在您的情况下,您似乎对了解每个CellCondition对象的索引并不感兴趣。因此,您可以使用相当于foreach循环的java:

for (CellCondition[] a : currentCondition)
{
    for (CellCondition b : a)
    {
        //Do whatever with b
    }
}
private static void ShowGrid(CellCondition[][] currentCondition) {
    int x = 0;
    int rowLength = 5;
    for(int i = 0; i < currentCondition.length; i++) {
        for(int j = 0; j < currentCondition[0].length; j++) {
            CellCondition condition = currentCondition[i][j];
            String output = (condition == CellCondition.Alive ? "O" : "·");
            System.out.print(output);
            x++;
            if(x >= rowLength) {
               x = 0; 
               System.out.println();
            }
        }
    }
}

只要进入牢房。每个单元都是一个CellCondition,而不是一个CellCondition[][]
