Question

The regular expression is (\\w+).*>(.{23}) ([^\\[]+)\\[([^\\]]+)]: (.+)

Pattern pattern = Pattern.compile("(\\w+).*>(.{23}) ([^\\[]+)\\[([^\\]]+)]: (.+)")
String s = "xxxxxx";   //this is what I want
Matcher matcher =  pattern.matcher(s);
System.out.println(matcher.find());   // I hope "true" 

Maybe it’s not suited to ask for help here. But I am not expert in regular expression and I need to know the result quickly.

I reduced the complexity and tried some schemes .

• abbb>(ccccccccccccccccccccddddddddddcc) is OK to (\\w+).*>(.{23})
• (\\a) is OK to ([^\\[]+)

but if I combine them.

abbb>(ccccccccccccccccccccddddddddddcc) (\\a) is not OK to (\\w+).*>(.{23}) ([^\\[]+)

So I am confused, especially the ([^\\[]+)\\[([^\\]]+)]: (.+) part.
Thanks .

Your question is very unclear, but if you needed strings to match your regular expression, I made some for you:

matches:true, string:word-0>kiOgNnuGfalhTfkqxtsCyhN f[RxQrH]: tqtmY
matches:true, string:word-1>wlnJomNExhCLHjrmsyLsKhh g[fXSsPYD]: BbzUM
matches:true, string:word-2>pdTepooJdeDgnODUAJMMPtB Pf[d]: aqmYx
matches:true, string:word-3>jMNDTuvCBufSEAxuzPDmyFG xt[T[RJjQEpJ]: bdlLS
matches:true, string:word-4>kHwqbjwNrSqhGeutzxtqiEy f[SmjJVt]: dWwlU
matches:true, string:word-5>UreUxUwpIyHqPXqVlALIlmr vuJScq[QFIpLCplW]: UuL0K
matches:true, string:word-6>dojPDeXqAfsHvGjOfvyZOtR aq[ImRqDn]: eyqlr
matches:true, string:word-7>ViljtcHRPzMjktFzqwDcprB le[U]: yfohG
matches:true, string:word-8>sjtQoCTupFbYqzhxcnrPbMh hhR[gufba]: DmREu
matches:true, string:word-9>ZauFhTHuvuXcqlymybjYHzj yv[FAaupu]: ZtrqL

all of them match "(\\w+).*>(.{23}) ([^\\[]+)\\[([^\\]]+)]: (.+)" and that list was generated by some code i wrote up real quick:

// generate some strings....
for (String string : full) {
    Pattern pattern = Pattern.compile("(\\w+).*>(.{23}) ([^\\[]+)\\[([^\\]]+)]: (.+)");
    Matcher matcher =  pattern.matcher(string);
    System.out.println("matches:" + matcher.find() + ", string:" + string);
}
