NoSuchMethodError Exception

Question

I keep getting a NoSuchMethodError Exception for the code shown below.
import java.util.*;
import java.lang.*;
import java.io.*;
public class test{
          private String readit()
// Set the default return value - a blank string
String input = "";
// Create an input stream reader to read from Standard Input (Keyboard)
InputStreamReader isr = new InputStreamReader( System.in );
// Create a buffered reader around the stream reader
// this allows you to read line at a time instead of char by char
BufferedReader br = new BufferedReader( isr );
try
input = br.readLine();
catch (IOException ex)
System.out.println( "Error reading keyboard input." );
return input;
     public void main(String args[]){
          try{
          String out = "Java is the best language in the world";
readit();
          int array[] = new int[5];
          for(int i = 0; i < 5; i++){
               array[i] = i;
               System.out.println(array[i + 1]);
               array[1] = -9;
          catch( ArrayIndexOutOfBoundsException e){
               System.out.println("Error ");
I don't know why this is but is something to do with calling the readit() method in main, Can anyone tell me how I could get around this or why this is happenning.

Answer 1

To get around javac compilation error, you can't make main method as non-static! You either have to
* create an object of your class and then call readit() on it
* or make readit() method as static as well.
