1. 声明并创建一个数组：src1，其内容为：1, 2, 3, 4, 5, 6 请用copyfRange方法复制该数组所有内容给另一数组dest1并输出dest

import java.util.Scanner; public class OK{static int[] copyOfRange(int[] original, int from, int to) { int i=0; int[] dest1=new int[to-from+1]; for(int z=from;z<=to;z++){ dest1[i]=original[z]; i++; } return dest1; } public static void main(String[] args){ Scanner in=new Scanner(System.in); int[] src1={1,2,3,4,5,6}; System.out.println("请输入要复制的范围下标:"); int i=in.nextInt(); int j=in.nextInt(); int[] dest1=copyOfRange(src1,i,j); System.out.print("数组dest1:"); for(int z=0;z<=j;z++){ System.out.print(dest1[z]+" "); } System.out.println(); }}

		System.out.println("请输入要复制的范围开始下标:");
		int i = in.nextInt();
		System.out.println("请输入要复制的范围结束下标:");
		int j = in.nextInt();
		if(i<0 || j>=src1.length) {
			System.out.println("范围越界！！！");

			System.out.println("开始下标不能大于结束下标！！！");
		}else {
			int[] dest1 = copyOfRange(src1, i, j);
			System.out.print("数组dest1:");

}

你main方法的for循环终止条件写错了

道友，看了你的程序，在下实在羞愧，细节做的太到位了，向你学习
