遍历数组–Arrays
import java.util.Arrays
遍历一维数组
Arrays.toString()
import java.util.Arrays;
public class Hello {
public static void main(String []args) {
int a[]={1,2,3};
System.out.println(Arrays.toString(a));
}
}
遍历多维数组（以二维数组为例）
Arrays.deepToString()
import java.util.Arrays;
public class HelloWorld {
public static void main(String []args) {
int a[][]={{1,2},{3,4}};
System.out.println(Arrays.deepToString(a));
}
}
输出多维数组的某一行（以输出二维数组的某一行为例）
import java.util.Arrays;
public class HelloWorld {
public static void main(String []args) {
int a[][]={{1,2},{3,4}};
int b[]=a[1];
System.out.println(Arrays.toString(b));
}
}
