學習使用Java中Arrays類方法運算元組

程式碼：

import java.util.Arrays; 
public class T2{
    public static void main(String args[]){
        int[]a={1,2,3,4,500,600,700,800};
        int[]b,c,d;
        System.out.println(Arrays.toString(a));
        b=Arrays.copyOf(a,a.length);
        System.out.println(Arrays.toString(b));
        c=Arrays.copyOf(a,4);
        System.out.println(Arrays.toString(c));
        d=Arrays.copyOfRange(a,4,a.length);
        System.out.println(Arrays.toString(d));
        c[c.length-1]=-100;
        d[d.length-1]=-200;
        System.out.println(Arrays.toString(a));
    }
}
