Scanner input = new Scanner(new FileReader(selectFile.getSelectedFile()));
int count = 0;
System.out.println("SampleName,RecordingTime,PeakName,Amount");
while(input.hasNext() && count <= 1000){
    count++;
    String word = input.next();

    if (count == 2){
        System.out.print(word + ",");
    }
    if (count == 36){
        System.out.print(word + ",");
    }

    if (count == 64){
        System.out.print(word + ",");
    }

    if (count == 68){
        System.out.print(word + ",");
    }

如何打印序列中的下一个单词？例如，程序读取如下文本文件。

你好

姓名：约翰金额：12.0

如何在姓名后打印单词：在这种情况下约翰或金额：12.0 提前致谢。

Answer 1

这是一种可以做到这一点的方法。

    while (input.hasNext()) {
        String word = input.next();
        Pattern pattern1 = Pattern.compile("Name:");
        Pattern pattern2 = Pattern.compile("Amount:");            
        Matcher matcher1 = pattern1.matcher(word);
        Matcher matcher2 = pattern2.matcher(word);
        if(matcher1.matches()){
            System.out.println(input.next());
        }
        if(matcher2.matches()){
            System.out.println(input.next());
        }           
    }
