Question

I have a Java program in which I need to accept the command line arguments in an array as input in the main method, and then need to pass the array to a constructor of another class in the same program. I need to know how to declare the array globally and then how to pass it and take it in the constructor.

Thanks

Answer 1

public class Example{

  Example(String s[])
  { 
   AnotherClass ac = new AnotherClass(s);
  }
  public static void main(String[] args){
  int num=args.length;
  String s[]=new String[num]; 
  Example ex = new Example (s);`
  }
}

And you can create AnotherClass

public class AnotherClass{
  AnotherClass(String s[])
  { 
   // array argument constructor
  }
}

You can run using

javac Example.java
