 String a =”GangBoard”;

String b =”Online Training”

Stirng C = a + b ;

it will create three separate memory in the Heap

Whereas

Stringbuilder s = new stringbuilder();

s.append(“GangBoard”);

s.append(“Online Training”);

//It will create single instance memory in the Heap

Answer:   A string is immutable means you cannot change it after it was created. Any operation that appears to change the string instead returns a new instance whereas when you need a mutable string, such as where you need to change lots of things, you use a StringBuilder which is a buffer of characters that can be changed.
