Question
In Java, you can create a String object as below :
Answers
String str = “abc”; &
String str = new String(“abc”);
Why can’t 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?
It is because “abc” is a literal string (something slightly different than a String object, by-the-way) and bt1 is a Button object. The only object in Java that can be assigned a literal String is java.lang.String   Your Comment
