I keep getting errors when I try to compile these codes below, I'm currently using JCreator.
import java.io.*;
public class Number //class name here, same as file name
{
public Number()throws IOException{//constructor, place class name here
// use BufferedReader class to input from the keyboard
// declare a variable of type BufferedReader
BufferedReader input = new BufferedReader(new InputStreamReader(System.in));
//declare variable for input
String inputString;
int number;
int counter;
int square;
int cube;
String goodMessage = "Thank you";
String badMessage = "Sorry";
//begin houseKeeping()
System.out.print("Please input number: ");
inputString = input.readLine();
number = Integer.parseInt(inputString);
//begin squareCube()
counter = 0;
while ((counter = 0)&&(number > 0)) {
square = number*number;
cube = number*number*number;
System.out.print(square);
System.out.print(cube);
}
if (counter = counter + 1);
if (counter < 3);
System.out.print("Enter input number: ");
//begin finishUp()
if (number > 0)
System.out.println(goodMessage);
else
System.out.println(badMessage);
}//end constructor
public static void main(String [] args) throws IOException // main method
{
new Number(); //class constructor name
} // end the main method
} // end the program
Error:
