if(" String ".trim() == "String")

System.out.println("Equal");

else

System.out.println("Not Equal");


why this prints not equal???
trim() method is to trim whitespace from the beginning and end of a string.

Hello,

Try this:



Note that I'm using the equals method.
Think about it. (Remember the object references concept)

the == operator ensure whether the memory location of both objects are same or not!
while the " String " and "String" both creates different memory addresses!

yes as Rafael mentioned.

.equals() ensure the content of both objects in general while the == checks memory reference!

i think thats because == sees if two refernces are pointing to same object...in this case they will both point to same string in the string pool but on the heap they are two different objects. Rafael's code will do.
