Mr. Cedric Moonen :) bellow is the code that l did compile and it works perfectly..thanks alot..

public class Calculate { public static void main(String[] args) { double x,y; if (args.length == 3) { x = Double.parseDouble(args[0]); y = Double.parseDouble(args[2]); if(args[1].equals("+")) { System.out.println("Answer = "+ (x + y)); }else if(args[1].equals("-")) { System.out.println("Answer = "+ (x - y)); }else if(args[1].equals("/")) { System.out.println("Answer = "+ (x / y)); }else if(args[1].equals("x")) { System.out.println("Answer = "+ (x * y)); } }else System.out.println("Do it again......"); } }

l've done it the code has compiled?

Mr. Cedric, I think u've tried alot best for me but l did try what u said and l got 3 error. anyway,l appreciate very well for ur help since am a beginner in java and once l cant compile this code those not make me to stop learning?please if u get anytime,try and correct this code for another people to lean from it? remain bless always from God.. I'll go back and learn the tutorials...thanks.

//l've change the code but still 1 error has been occur public static void main(String [] args) { String sign; int num1; int num2; //int num3; int ans; System.out.print("Enter your Calculations =>: \n"); sign = in.nextLine(); if(args.Length == 3) { num1 = Integer.parseInt(args[0]); sign = (args [1].equal("1")); num2 = Integer.parseInt(args[2]); //num3 = Integer.parseInt(args[3]); System.out.println("Answer = "+ ans); }else if(args[0].equal("+")) { ans1 = num1 + num2; System.out.println("num1 "+ "num2 " = ans); } else if(args[1].equal("-")) { ans2 = num1 - num2; System.out.println("num1 "- "num2 "= ans); } else if(args[2].equal("/")) { ans3 = num1 / num2; System.out.println("num1 "/ "num2 "= ans); } System.err.println("Try Again"); } } }

Mr. Cedric please a question? 1- how should make the sign veriable work and? 2- how to initialize those to variables( num1 and num2)?

thanks again.. l dont wont u to write all the program for for but to guide me Fix the errors is all what l need..but thanks alot for ur time becouse this's my first time of sending a code in this forum...

thanks alot Mr. Cedric the reason for this code is that l wonted to do CALCULATING IN JAVA? l understand u completely but for now,how should l make the code work(l mean to initialize it)and not to fall back the way l was before? thanks for ur alert for the tutorials.please help me for this one...

please pancakeleh, how did u do it?show as the code please...thanks alot..

thanks but where should u put all this code(mean to put it inside the try and catch or where...)

// I need someone to help me fix this codes // it's about CALCULATING in Java, thanks alot...

import java.util.Scanner; public class Calculate { static Scanner in = new Scanner(System.in); public static void main(String [] args) { String sign; int num1; int num2; int num3; int ans; System.out.print("Enter your Calculations => \n"); sign = in.nextLine(); if(args.Length == 3) { num1 = Integer.parseInt(args[0]); sign = (args [1].equal("1")); num2 = Integer.parseInt(args[2]); num3 = Integer.parseInt(args[3]); ans = num1 + num2; ans = num1 - num2; ans = num1 / num2; System.out.println("Answer = "+ ans); }else if(args[1].equal("+")) { ans = num1 + num2; System.out.println("num1 "+ "num2 " = ans); } else if(args[2].equal("-")) { ans = num1 - num2; System.out.println("num1 "- "num2 "= ans); } else if(args[3].equal("/")) { ans = num1 / num2; System.out.println("num1 "/ "num2 "= ans); } else if("Do it again => Calculate arg1, arg2, arg3"); } } }
