Which of these method of class String is used to check whether a given object starts with a particular string literal?

To determine whether a given object of type String starts with a particular string literal, the method you would use is startsWith(). This method is part of the String class in Java. It checks if the string begins with the specified prefix.

Explanation:

1. Method Signature: The startsWith() method has the following signature:

   boolean startsWith(String prefix)
   

   It returns true if the string begins with the specified prefix; otherwise, it returns false.

2. Overloaded Version: There is also an overloaded version of this method:

   boolean startsWith(String prefix, int toffset)
   

   In this version, the toffset parameter indicates the position in the string from which to begin checking for the prefix.

3. Usage: For example:

   String str = "hello world";
   boolean starts = str.startsWith("hello"); // returns true
   

Using startsWith() is a straightforward way to check for string prefixes in Java, making it a commonly employed method in string manipulation.

Final Answer

The method used to check if a String object starts with a particular string literal is startsWith().
