如何输入一个数组
假设要输入一组数进行快速排序:
public static void main(String[] args) {
Digui digui = new Digui();
System.out.println("请输入一行数字,用逗号隔开:");
Scanner scanner = new Scanner(System.in);
String[] split = scanner.next().split(",");
int[] a = new int[split.length];
for(int i=0;i<split.length;i++){
a[i] = Integer.parseInt(split[i]);
}
System.out.println("排序前:\n"+ Arrays.toString(a));
digui.quickSort(a, 0, a.length-1);
System.out.println("排序后:\n" + Arrays.toString(a));
}
运行结果:
