关于java:java-Arrays

Arrays 实用功能

public class CopyingArrays {public static void main(String[] args) {int[] i = new int[7];
        int[] j = new int[10];
        Arrays.fill(i, 47);// 填充
        Arrays.fill(j, 99);
        System.out.println("i="+Arrays.toString(i));// 转换成字符串打印
        System.out.println("j="+Arrays.toString(j));
        System.arraycopy(i,0,j,0,i.length);// 复制
        System.out.println("j="+Arrays.toString(j));
        System.out.println(Arrays.equals(i,j));// 比拟
 }
}

数组元素比拟
