Why do I get the error "error: cannot find symbol"?

Question

I have two files first one is

Welcome.java

package com.project;

import com.code.*;

class Welcome {
    public static void main(String[] args) {
        Test t = new Test();
        System.out.println("the valus is " + t.addition(4,3));
    }
}

Test.java

package com.code;

public class Test {
    private int a;
    private int b;
    public Test() {
        a=2;
        b=3;
    }

    public int addition(int a, int b) {
        return a+b;
    }
}

When I compile Welcome.java I got:

error: cannot find symbol

System.out.println("the valus is " + t.addition(4,3));

Cannot find the reason why ? help please

Edit:

I compile with this command:

javac com/project/Welcome.java

Solution:

javac -cp com/code/* com/project/Welcome.java

Please post the full stack trace. Is `com.code` in the classpath? — BackSlash, Jan 06 '18 at 23:10

@hoefling have found that link before but doesn't help at all. — Martin.B, Jan 06 '18 at 23:23
@Martin.B You need every thing to be in public if you're getting a method from another class. Also try an IDE. — , Jan 06 '18 at 23:24
the class is well recognized as the error concerns the function addition and not the class Test. — Martin.B, Jan 06 '18 at 23:25
@Martin.B Could you post the solution as a self-answer instead of editing it in and mark it as accepted? See https://stackoverflow.com/help/self-answer — LW001, Jan 06 '18 at 23:41

At Test, the addition method should be public int addition(int a,int b)

It doesnt change anything. – Martin.B Jan 06 '18 at 23:14
Add public to the Test() method as well – Or251 Jan 06 '18 at 23:17
before commenting please try to compile it. – Martin.B Jan 06 '18 at 23:23
I actually compiled and run this, it's working :D use Eclipse or Intelij if you are having problem compiling from cmd, much easier and user freindly – Or251 Jan 06 '18 at 23:27
