All string literals in Java programs, such as "abc", are implemented as instances of this class. Strings are constant; their values cannot be changed after they are created. String buffers support mutable strings. Because String objects are immutable they can be shared. For example: String str...
In Java, strings are objects. Just like other objects, you can create an instance of a String with the new keyword, as follows: Step 1 String name = new String(“Amit”); String name = "Amit"; This line of code creates a new object of class String and assigns it to the reference...
