Re: check if string contains another string Reply #3 - Feb 21st, 2010, 10:04pm   It is the most common way. It might be worth mentioning also the more friendly .startsWith() and .endsWith(), the latter being perfect to check file extensions... Ah, I had a vague recall... Yes! In Java 1.5 (you should check the latest versions of Java API...), Sun introduced the contains method, symmetrical to starts/endsWith...
