JAVA : SELENIUM : Correct way to declare and initialize a String variable named "message" with a value of "Hello World" in Java?
a) String message = "Hello World";
b) message = "Hello World";
c) string message = new string("Hello World");
d) String message = new String("Hello World");
Answer: (a) String message = "Hello World";
Explanation:
Option (b) is incorrect because it is missing the type declaration.
Option (c) is incorrect because it is using the wrong class name and syntax to create a new instance of the String class.
Option (d) is incorrect because it is using the constructor of the String class to create a new instance, which is unnecessary since string literals are automatically converted to String objects.
Option (a) is the correct way to declare and initialize a String variable in Java, using the type declaration "String", the variable name "message", the assignment operator "=", and the value "Hello World" enclosed in double quotes.
