could not find or load main class.java

Question

I have two classes for function overloading in JAVA namely ABC and XYZ. XYZ class has the function overloading methods whereas ABC class has the main method. I have saved the file as ABC.java. The program do compiles but shows an error "could not find or load main class ABC" during runtime. I have also attached my code to be specific.

class XYZ
{
   void pqr(int a, int b)
   {
      int res = a*b;
      System.out.println("The result is "+res);
   }
   void pqr(String a, String b)
   {
     System.out.println("The concatenated string is "+a+b);
   }
   void pqr(int a, int b, int c)
{ 
int res = a+b+c;
    System.out.println("The final result is "+res);
}
}

class ABC

{
 public static void main(String[] args)
{
    XYZ a = new XYZ();
    a.pqr(10,20);
    a.pqr("Pratik","Paul");
    a.pqr(20, 40, 60);
 }

}

Answer 1

Follow the below steps,

Step1:

go the bin folder of Java from command prompt(I assume you are trying to run the program from command prompt).

ex: C:\Program Files\Java\jdk1.8.0_05\bin

Step2:

javac <your ABC.java file with full path>

ex: javac C:\Test\ABC.java

similary do for XYZ.java

Step3:

Go to C:\Test\ from command prompt and run,
java ABC
