Question: I want to search a word inside a string :
For example let the String be `"ThisIsFile.java"`
and let i want to search `"File.java"` or `"IsFile"`

This is something like sql `'like'` query but unfortunately i am not 
getting that string from database.

Please suggest me any good solution for this.
Thanks

Answer: 
There's a variety of ways of achieving this and the method you choose will depend on the complexity of your queries. For a simple plain symbol/word match the String class provides a contains method that takes a single parameter, the String to search for - and returns true if it occurs within the search String.

```
bool containsFile = myString.contains("file");

```
You should be able to use 

```
String.contains("some string");

```
