How to open notepad using java program

Posted by: Instanceofjava Posted date: 9:48 PM / comment : 0 ,

  • Notepad is a text editor from windows operating system. We use notepad for writing text files.
  • We can open a new notepad using java code.
  • By using the concept of running another application by Runtime class in java.
  • By creating object of runtime and calling  exec() method by passing application name.
  • Lets see how to open a notepad using java code




Program #1: Java example program to open notepad


  1. package interestingJavaprograms;
  2. import java.io.IOException;
  3.  
  4. public class NotepadJava {
  5.  
  6.     /**
  7.      * @ www.instanceofjava.com
  8.      * @ how to open a new notepad using java program
  9.      */
  10. public static void main(String[] args) {
  11.        
  12.           Runtime rt = Runtime.getRuntime();
  13.           
  14. try {
  15.       rt.exec("notepad");
  16. }
  17.  catch (IOException ex) {
  18.  
  19.  System.out.println(ex);
  20.  
  21. }  
  22.  
  23. }
  24.  
  25. }

 Output:

Program #2: Java example program to open notepad and after 2 seconds close it.
  1. package interestingJavaprograms;
  2. import java.io.IOException;
  3.  
  4. public class NotepadJava {
  5.  
  6.     /**
  7.      * @ www.instanceofjava.com
  8.      * @ how to open a new notepad using java program
  9.      */
  10. public static void main(String[] args) throws InterruptedException, IOException {
  11.         
  12. Runtime runTime = Runtime.getRuntime();
  13. System.out.println("Opening notepad");
  14. Process process = runTime.exec("notepad");
  15.           
  16. try {
  17.  
  18.  
  19. Thread.sleep(200); 

  21.  process.destroy();
  22.  System.out.println("Closing notepad");
  23.  
  24. }
  25.  catch (Exception ex) {
  26.  
  27.  System.out.println(ex);
  28.  
  29. }  
  30.  
  31. }
  32.  
  33. }

  • We can open already existing notepad also for that we need to specify notepad.exe location and path of the destination file.
  • We need to pass these two parameters  to exec method of runtime class.
  • runTime.exec("C:\\Windows\\System32\\notepad.exe E:\\Samplenotepad.txt");

Core java online programming test on inheritance

Posted by: Instanceofjava Posted date: 12:02 PM / comment : 0 , ,

  • Inheritance means getting properties from one class object to another.
  • So in sub class we can use or access super class variables and method : re usability
  • There are some interesting and important points to discuss about inheritance
  • In major java interviews and java online test on core java there is more chance of getting programming questions from inheritance
