Regex pattern matches() method java

Question

I'm trying to find the regex in java that matches a substring with TTFI within a string TTFI

I'm using /TTFI/ to match the string TTFI in a string such as TTFI1233

When using the folllowing URL http://www.regexplanet.com/advanced/java/index.html to check, it results matches() No

The fiddle URL is : http://fiddle.re/e3y2

Thanks, Nav

反斜杠不是正则表达式的一部分，而是perl，javascript等中使用的特定于语言的分隔符。还要注意，Java RE要求整个字符串都匹配-使用.*TTFI.*可以完美匹配您的输入。
