6월28일 자바(예외처리

package net.itisn;

public class Greeting {
  static String greet(String name)
  {
    return "안녕하세요"+name+"님";
  }
  public static void main(String[] args) {
    if(args.length==0)
    {
      System.out.println("usage : java Greetin<name>");
      System.exit(1);
    }
    String msg =greet(args[0]);
    System.out.println(msg);
  }

}

우리가 C를 사용할때 main abc fsd 라고 할때
int main (args[])로 인해 main이 args[0]이다 하지만
자바에서는 args[0]이 바로 abc가 된다.
