​​The string is among the most frequently used classes in Java. Thus, it is essential for you, as a beginning coder, to learn and understand different string functionalities to use them properly.

Continuing with the Java series, today we give a tutorial on how to return a string in Java.

Check it now!

What Does “Return A String” Mean?

A return is a value returned by calling a script or function after it is done. The value is either of four variable types: string, object, integer, or handle – depending on the data types specified in the declaration.

The string data type we discuss in this article is a string or a sequence of elements, usually connected characters. If the return type is a string, the return value is preceded by the string in ” “double quotations such as “Hello World”; “abc123”; or “How to return a string in Java?.”

How To Return A String In Java?

We would like to give examples and explain to you how to return a string in Java.

public class ReturnString {
  public static void main(String[] args) {
    String studentName;
    studentName = fullName("Stepphanie", "Greence");
    /**
    We are using the fullName method that accepts arguments of a string, including first name and last name and concatenates them into a string object. The first @parameter is the first name, and the other @parameter is the last name.
    */
    System.out.println(studentName);
  }
  public static String fullName(String first, String last) {
    String name;
    name = first + " " + last;
    return name;
    /**
    @return A reference to a String object combined from the first and last names.
    */
  }
}

Our purpose is to return the string StudentName.

• In the driver class above, we define a public function ReturnString that returns a String value. The public keyword indicates that the return values are visible.
• In the driver class above, we define a public function ReturnString that returns a String value. The public keyword indicates that the return values are visible.
• The static keyword is not mandatory, so the returning method can be called without generating the driver class instance. The main function is a fixed value directly called without the need for the driver class’s name.
• Continue to define the structure of students’ names following the fullName method – joining the first and last names.
• The line System.out.println(studentName) is to print the string method.
• return type is the next value. The type states which primitive data can be returned. In our example, the return type is a string fullName.
• Name the method. You can choose any name, excluding pre-fixed keywords in Java. Above, the string name is “name” containing the parameters passed first + ” ” + last.
• The return statement is the last line, and the return keyword is preceded with “”double quotations.
• Wrap the returning function’s beginning and end using curly braces {}.

Final Words

The example is simple yet helpful in understanding how to return a string in Java. You can refer to the sample itself and the explanation to write your own string returning method.
