Optional Parameter in Java.

Question

Hi all,
I am new to java programming... I just wanted to know if we can have Optional parameter in java?. I searched few threads but not found any good result. Few suggested a overloaded method ,i think if it is not provided then there must be a big reason for that. Please let me know if anybody knows exact reason why it is not provied. I am using ver 1.4

Answer 1

class A{
     String a;
     String b;
     String c;
     public A(String a, String b, String c){
          this.a=a;
          this.b=b;
          this.c=c;
     public A(String a, String b){
          this.a=a;
          this.b=b;
          //String c will get a default value when this constructors get called
     public static void main(String args[]){
          A test = new A("a","b","c");
          System.out.println(test.a);
          System.out.println(test.b);
          System.out.println(test.c);
          System.out.println("-------");
          A test_ = new A("a","b");
          System.out.println(test_.a);
          System.out.println(test_.b);
          System.out.println(test_.c);
}Is that what you want?
