String Pattern Matching In Java

[Sarika Sukumaran]

I want to search for a given string pattern in an input sting.
For Eg.

String URL = "https://localhost:8080/sbs/01.00/sip/dreamworks/v/01.00/cui/print/$fwVer/{$fwVer}/$lang/en/$model/{$model}/$region/us/$imageBg/{$imageBg}/$imageH/{$imageH}/$imageSz/{$imageSz}/$imageW/{$imageW}/movie/Kung_Fu_Panda_two/categories/3D_Pix/item/{item}/_back/2?$uniqueID={$uniqueID}"

Now I need to search whether the string URL contains "/{item}/". Please help me.
This is an example. Actually I need is check whether the URL contains a string matching "/{a-zA-Z0-9}/".
I need to check this pattern "/{a-zA-Z0-9}/". The pattern should include two slashes and two braces. But the letters can be anything.
For eg: "/{asdFs7f}/", "/{asdfg}/", "/{ASDF}/", "/{23445}/".
Please help me suddenly.

Sounds like a perfect use case for regular expressions: http://download.oracle.com/javase/tutorial/essential/regex/index.html

Something like "/{[a-zA-Z0-9]+}/" should work as the pattern, although you may have to escape a few of the characters.

The following should be your regex. But as Tim suggested, reading java.util.regex API gives you better understanding why
it is written in such a way. check this link to know why the above poster asked you to escape some characters .
Java regex special characters

"/\\{[a-zA-Z0-9]+\\}/"
