Java正则表达式无法找到“Ts”后跟“kb”

I have to convert "Tskb" to "TsKB" using java regex whenever it comes as single word. I have written below code which not working.

我必须使用java正则表达式将“Tskb”转换为“TsKB”，只要它是单个单词。我写下面的代码不起作用。

    public class TestBGR {
    private static final Pattern s_TsKB = Pattern.compile("/(Ts?.*)(?=.*kb)^(\\w+)$/");
    public static void main(String[] args) {

        String text = "Tskb";
        Matcher       matcher = s_TsKB.matcher(text);
        StringBuilder builder = new StringBuilder(text);
        int           offset  = 0;

        while (matcher.find())
        {
        String replacement = "KB";      
        builder.replace(matcher.start() + offset, matcher.end() + offset,
                        replacement);       
        offset += replacement.length() - matcher.group().length();
        }       
        System.out.println(builder);
    }
}

Here how to find "Ts" followed by "kb" using java regex..?

You can simply do a replaceAll with

你可以简单地用replaceAll做

(?<=\\bTs)kb\\b

and replace by KB.The lookbehind will make sure kb has Ts before.

并且用KB代替。lookbehind将确保kb之前有Ts。

See demo.
