Array in java Array is a variable that can hold more than one value at a time. Declaration :    int arr[] = {elements}    or    int [] arr = {elements} Intialization :    int arr[] = {2, 4, 6, 7,}     Example :    public class arrLesson {                public static void main(String           args[]) {                // declares an array                 int arr[] = { 2, 3, 2, 9, 3 };                                 for ( int i=0; i < arr. length ;       i++)      {                      /* outputs each element                     ...

class  plus{   static   int  add( int  a, int  b) {     return  a+b; }      static   int  add( int  a, int  b, int  c)     {       return  a+b+c;    }   }   class  Overloading1 {   public   static   void  main(String[] args)    {         //access the add method with 2 param from class plus,      //pass 2 arguments and print the return value      System.out.println (plus.add( 10 , 10 ));         //access the add method with 3 param from class plus,        //pass  3 arguments and print the return value       System.out.println (plus.add( 10 , 10 , 10 ));       } }   It will produce the following results: 20 30
