 //You can try other string that you want by change aaAAA
 String firstString="aaAAA";

 //Create second String = AAaaa
 //You can try other string that you want by change AAaaa
 String secondString="AAaaa";

 //Check if first String is same or not to second String
 if(firstString.equalsIgnoreCase(secondString))
 {
  //If first String equal to second String, it will print ( firstString is same to secondString )
  System.out.println("firstString is same to secondString");
