it doesn’t change the value of original String. It creates a new String in the string pool and change the reference of the variable. So original string value is never changed and that’s why Strings are immutable. Below program proofs our statement, read...

"Hello World"is called aStringliteral. In a Java program, everything between two double quotes is aStringliteral. Literals are implemented as instances of String class. As you can see, you can conveniently initialize aStringObject like a primitive type, e.gint i = 0;. There is no need t...
