In this Tutorial we want to describe you a code that help you in understanding the java error message. For this we have a class name java error message. Inside the class we have a main method that consists of-

1)InputStreamReader-The input stream reader is used to read the byte code that is used to encode the byte code into character stream.

2)Buffered  Reader   - The Buffered reader is used to read a text from a character input Stream reader.

3)readline   -The readline is used to read a number printed by System.out.println on the output of a command prompt.

On execution of code the program code show an error, identifier expected for a number, as we do not declare the data type of num. and illegal start of type  as we do not place the braces after the main static method.

javaerrormessage.java

import java.io.*;
public class javaerrormessage {

  public static void main(String args[]) throws Exception 
 
  InputStreamReader inputStreamReader = new InputStreamReader(System.in);
  BufferedReader br = new BufferedReader(inputStreamReader);

  System.out.println("Enter a number : ");
  String num = br.readLine();

  int j = Integer.valueOf(num);
  for (int i = 0; i < j; i++) {
  System.out.println(i);
  }
  }

}

Output

Compiling source file to /home/girish/NetBeansProjects/errors/build/classes
/home/girish/NetBeansProjects/errors/src/javaerrormessage.java:4';' expected
  public static void main(String args[]) throws Exception 
/home/girish/NetBeansProjects/errors/src/javaerrormessage.java:9: <identifier> expected
  System.out.println("Enter a number : ");
/home/girish/NetBeansProjects/errors/src/javaerrormessage.java:9: illegal start of type

To resolve this error you have to give Brace after public static void main(String args[])throws Exception {
