1. nextInt()方法读取一个数后就按任意字符都会结束;
2. nextLine()方法读取一行,以enter结束;
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int T = Integer.parseInt(scanner.nextLine());//单个数字输入
while (T > 0) {
String input = scanner.nextLine();//整行输入
int n = Integer.valueOf(input.split(" ")[0]);
int k = Integer.valueOf(input.split(" ")[1]);
input = scanner.nextLine();
int[] nums = new int[n];
String[] strings = input.split(" ");
for (int i = 0; i < n; i++) {
nums[i] = Integer.valueOf(strings[i]);
}
T--;
//调用
System.out.println();
}
scanner.close();
