Java示例返回数组深层内容的字符串表示形式
返回指定数组深层内容的字符串表示形式-
示例
import java.util.Arrays;
public class Demo {
public static void main(String[] args) {
Object[] ob = {"One","Two", "Three", "Four"};
System.out.println("Array elements...");
for (Object value : ob) {
System.out.println("Value = " + value);
}
System.out.println("数组的字符串表示形式是：");
System.out.println(Arrays.deepToString(ob));
}
}输出结果
这将产生以下输出-
Array elements... Value = One Value = Two Value = Three Value = Four 数组的字符串表示形式是： [One, Two, Three, Four]
示例
现在让我们来看另一个示例-
import java.util.Arrays;
public class Demo {
public static void main(String[] args) {
int[][] arr = new int[3][3];
arr[0][0] = 10;
arr[0][1] = 20;
arr[0][2] = 30;
arr[1][0] = 40;
arr[1][1] = 50;
arr[1][2] = 75;
arr[2][0] = 100;
arr[2][1] = 150;
arr[2][2] = 200;
System.out.println(Arrays.deepToString(arr));
}
}输出结果
这将产生以下输出-
[[10, 20, 30], [40, 50, 75], [100, 150, 200]]
