Java 如何从二维数组中获取特定行？

我想将第一行数组值存储到resultArray，如何在java中实现这一点。请帮助我

尝试：

String[][] array = {{"a","b","c"},{"d","e","f"},{"g","h","i"}};
String[][] resultArray = [10][10];

如果要复制，您需要迭代或使用

clone

尝试以下操作：

复制参考文件

String[][] array = {{"a","b","c"},{"d","e","f"},{"g","h","i"}};
String[] resultArrayPtr = array[index];

复制值

String[][] array = {{"a","b","c"},{"d","e","f"},{"g","h","i"}};
String[] resultArray = array[0];

String[]firstRow=array[0]您的resultArray是一个二维数组。我想将数组变量的第一行存储到resultArray变量的第一行，而不使用indexingWell…然后您必须对值进行硬编码，如下所示：
String[]resultArray={“a”、“b”、“c”}在ResultaryPtr中，如何将数组的第一行存储到数组的第一项resultArrayPtr@Sathesh通过设置
index=0？
String[][] array = {{"a","b","c"},{"d","e","f"},{"g","h","i"}};
String[] resultArray = array[0];

String[][] array = {{"a","b","c"},{"d","e","f"},{"g","h","i"}};
String[] resultArray = new String[array[0].length];
System.arraycopy(array[0],0, resultArray, 0, array[0].length);
