Java Instance Practice

1. Do not use intermediate variables to exchange two numbers

 Public classExchange { Public Static voidMain (string[] args) {Scanner Scanner=NewScanner (system.in); System.out.println ("Please enter an integer:"); Long NUM1=Scanner.nextlong (); System.out.println ("Please enter an integer:"); Long num2=Scanner.nextlong (); System.out.println ("Num1 before Exchange:" +num1+ "before num2:" +num2); NUM1= num1^num2; Num2= num2^NUM1; NUM1= num1^num2; System.out.println ("Num1 after Exchange:" +num1+ "after Exchange num2:" +num2); }}

Exchange

2. Using the trinocular operator to determine parity

 Public class ParityCheck {    publicstaticvoid  main (string[] args) {        new  Scanner (system.in);        System.out.println ("Please enter an integer:");         = Scanner.nextlong ();         = (num%2==0)? " This number is: even ":" This number is: odd ";        System.out.println (s);    }}
