条件正则表达式使用Java匹配文本输入流中的组，忽略格式错误的行

Question

在练习了regex tester之后，我发现以下模式[a-zA-Z+[^ \t]+0-9]能够匹配我感兴趣的组：

我试着用如下方式“Java化”它：Pattern.compile("(a-zA-Z)( \t)(0-9)");，不确定这是不是正确的方式。。。但稍后会有更多关于这方面的内容

我的输入流如下所示：

因此，我不仅要匹配大空格前后的两个不同部分的行（实际上是三个连续的制表符），而且我还要忽略不符合该模式的每一行，即“^{，“^{，“^{”

我试着这样做：

for (String k : debugOutput) {
    Pattern pattern = Pattern.compile("(a-zA-Z)( \t)(0-9)");
    Matcher matcher = pattern.matcher(k);
    while (matcher.find()) {
        System.out.println("group 1: " + matcher.group(1));
        System.out.println("group 2: " + matcher.group(2));
        System.out.println("group 3: " + matcher.group(3));
    }
}

但这是行不通的——它不会吸引我想要的群体，也不会忽视我试图避免的台词

将模式更改为：

Pattern pattern = Pattern.compile("([a-zA-Z]+)(\\s+)([0-9]+)");

如果输入行等于

String input = "makePush            2196";

它会打印

group 1: makePush
group 2:             
group 3: 2196
