java - 在没有 EOF 的情况下停止在 java 中读取输入

Question

在this问题，我如何停止阅读输入？我的程序一直在运行，要求更多输入。

public static void main(String[] args) throws Exception {
    BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
    String src;

    while ((src = br.readLine()) != null) {
        String trgt = br.readLine();
       //do something
        }
    }

像这样，

public static void main(String[] args) throws Exception {
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
String src;

while ((src = br.readLine()) != null) {
    StringTokenizer st=new StringTokenizer(src);
    if(!st.hasMoreTokens()) break;
    //YOUR LOGIC GOES HERE 
    }
}
