RE: [java prob]guna user input dan methode erroe indintifier
PHP Code:
import java.io.*;
class 
calculator{
    
    
int aConvert,bConvert



    
void readInput() throws IOException{
    
    
BufferedReader stdin=new BufferedReader(new InputStreamReader(System.in));
    
String a,b;

    
System.out.println("masukan nilai a: ");
    
a=stdin.readLine();
    
aConvert=Integer.parseInt(a);
    
System.out.println("masukan nilai b: ");
    
b=stdin.readLine();
    
bConvert=Integer.parseInt(b);
    }
    
void add()
    {
    
System.out.println("hasil tambah dua nilai "+(aConvert+bConvert));
    }
    public static 
void main(String[] argsthrows IOException
    
{
    
calculator c1=new calculator();
    
c1.readInput();
    
c1.add();
    }
    } 

ko nya silap first ko x letak nama method.. ini contoh nama method aku kasi.
Code:
void readInput() throws IOException{

Pastu ko silap declare variable.sepatutnya ko kena set variable tu jd instance variable. Kalo ko x set jd instance variable nnt method void add() x leh nk jumpa ko nye variable.
Code:
int aConvert,bConvert;
