我想要做的是:
2 (number of test cases)
4 7 8 15 16 (test case 1)
here will be output, for example will print the max number
7 97 1 2 9 (test case 2)
here is output again
我会在每个测试用例中都有一些语句,直到用户按Enter键.我看到了一些类似的问题,但我尝试过的解决方案都没有用.
这是我最后尝试过的:
Scanner cin = new Scanner(System.in);
int test = Integer.parseInt(cin.nextLine());
for (int k = 0; k < test; k++) {
while (cin.next() != "\\n") {
int number = cin.nextInt();
//do something
}
//print output
}
最佳答案 您可以读取整个输入行,然后创建一个新的Scanner来读取此行中的整数:
Scanner cin = new Scanner(System.in);
int test = Integer.parseInt(cin.nextLine());
for (int k = 0; k < test; k++) {
String line = cin.nextLine();
Scanner lineScan = new Scanner(line);
while (lineScan.hasNextInt()) {
// print number
System.out.println(lineScan.nextInt());
}
//print output
}
