In multiple returns which one gets the final return value?

[kamina23]

Hello to all,
I recently started learning java language. I have one problem in following code.

String test() {
    try {
        return "one";
    } finally {
        return "two";
    }
}

I want to asked whether above code define the return value of a call to test()? It means in multiple returns which one gets the final return value? Please help me.
Thank you.

As per my information from above code in multiple returns two is the return value. It means language specification defines that "2" is the result. It is does not depend on Virtual machine, because it is not spec-compliant. If you are tried to execute above code then return block will never be executed. In this case try to write simple code to avoid such situation.

Hey remember that the finally block will always be executed last, but not in the program like following

String testEg() {
    try {
        Systems.exit(0);
    } finally {
        return "two";
    }
}

In above code the java virtual machine will stop without executing the finally block. In your above code the return value will be 2.

When you use finally block in your code along with return function, the value return by finally block replace whatever you might have returned from the try or catch block. The same type of concept is apply for exceptions. Whenever you throw value in the finally block, that particular exception will replace all values was thrown in the try or catch block. So be careful while passing any value to finally block.

From you information your code returns value "2". I think finally block will never execute. If you are tried to run this code in Visual Studio, then it will show an warning telling it as unreachable code. If you execute this code normally then it will not give any error message. If you tried to run code in Netbeans, the you will get warning: "Finally clause cannot complete normally".

You have written wrong code and that's why you are getting such type of problem. In this case you have to write following code to get rid out of this problem. In the following code I have use StudentEg class to include all methods.

package onlineResult;

public class StudentEg
{
   String names;
   String grades;
   String courses;

   public StudentEg()
   {}

   public Student(String names,String grades,String courses)
   {
      this.names = names;
      this.grades = grade;
      this.courses = course;
   }

   public String getName()
   {
      return names;
   }

   public void setName(String names)
   {
      this.names = names;
   }
   public String getGrade()
   {
      return grades;
   }

   public void setGrade(String grades)
   {
      this.grade = grades;
   }
   public String getCourse()
   {
      return courses;
   }

   public void setCourse(String courses)
   {
      this.courses = courses;
   }

}
