 JAVA CODE - TABLE OF A NUMBER: import java.util. Scanner ; class TableOfNumber {     public static void main ( String [] args )     {         Scanner sc = new Scanner ( System . in );         System . out . println ( "Enter a Number" );         int num = sc . nextInt ();         if ( num > 0 )         {             for ( int i = 1 ; i <= 10 ; i ++ )             {                 System . out . println ( num + " * " + i + " = " + num * i );             }         }         else         {             System . out . println ( "Wrong Number" );         }     } }

Easy way to solve TECH NUMBER program.   import java . util . Scanner ;   public class TechNumber {   public static void main ( String args [])   {   int n , num , firstHalf , secondHalf , digits = 0 , squareOfSum = 0 ;   Scanner sc = new Scanner ( System . in );   System . out . print ( "Enter a number to check: " ); n = sc . nextInt ();   num = n ;     while ( num > 0 )   {         digits ++ ;   num = num / 10 ;   }     if ( digits % 2 == 0 )   {   num = n ;   firstHalf = num % ( int ) Math . pow ( 10 , digits / 2 ); secondHalf = num / ( int ) Math . pow ( 10 , digits / 2 );   squareOfSum = ( firstHalf + secondHalf ) * ( firstHalf + secondHalf );   if ( n == squareOfSum )   {   System . out . println ( n + " is a tech number." );   }   else   {   System . out . println ( n + " ...
