java - 停止键盘输入？

Question

Scanner s = new Scanner(System.in);
List<Integer> solutions = new LinkedList<>();
int o = 0;

while (o != 10) {        // I want to read 2 numbers from keyboard   
    int p = s.nextInt(); // until send and enter, this is where is my
    int c = s.nextInt(); //doubt
    int d = p + c;
    solutions.add(d);  
    o = System.in.read();
}

Iterator<Integer> solution = solutions.iterator();
while (solution.hasNext()) {
    int u = solution.next();
    System.out.println(u);
}

我遇到的问题是，如何发送 Enter 来结束循环？因为如果我输入另外 2 个数字，则 System.in.read() 会获取第一个数字，示例可能是，

条目:

2 3(输入)读取2个数字并求和

1 2(输入)读取2个数字并求和

(输入)这里结束循环，因为输入并且没有数字，并给出了解决方案

退出:

读整行并自己解析。如果该行为空，则退出循环并结束程序。如果它不为空，则将该行传递给新的扫描仪。

List<Integer> solutions = new LinkedList<>();

Scanner systemScanner = new Scanner(System.in);
String line = null;

while ((line = systemScanner.nextLine()) != null && !line.isEmpty()) {
    Scanner lineScanner = new Scanner(line);
    int p = lineScanner.nextInt();
    int c = lineScanner.nextInt();
    int d = p + c;
    solutions.add(d);
}

Iterator<Integer> solution = solutions.iterator();
while (solution.hasNext()) {
    int u = solution.next();
    System.out.println(u);
}
