Question

Create your own Java program that has all three of these components in its design:

• Includes file input OR file output (one of the two)
• Uses token-based processing of String, int, double, or boolean (your choice)
• Incorporates two additional methods in addition to the main() method: one that's a value-returning method, the other a void.

Answer 1

The code for the above program is given below and comments are added in code for your understanding:

import java.io.FileInputStream;

public class MemberTest {
     

   public static void main(String[] args) {
      
       ///example of fileinput
       try{
   FileInputStream input=new FileInputStream("filehello.txt");
   int i=input.read();
   System.out.print((char)i);
  
   input.close();
   }catch(Exception e)
               {
       System.out.println(e);
       }
       //example of file input ends
  
      
   }
  
   //this is the method which return some value
   public int valueReturning()
   {
       return 8;
      
   }
   //this is the method for void
   public void hello()
   {
       System.out.println("Hello from void");
   }
      
  
}

Please refer to the screenshot of the code for identation of the code:
