Hi.....................

Ques: I am create a String object as below ...........
String str = "abc"; & String str = new String("abc"); Why can not a button object be created as : Button bt = "abc"? Why is it compulsory to create a button object as: Button bt = new Button("abc"); Why this is not compulsory in String's case?

Java is a strongly typed language.

The line:

Button bt = "abc";

makes no sense as bt is a Button variable and "abc" is a string. There is no implicit conversion between the two types.

However, in the case of Strings, you are allowed to assign a String literal such as "abc" directly to a String variable. This is still type safe and is (in effect) an abbreviation for new String("abc").
