Java input and output

Enter to define a scanner

Scanner sc= New Scanner (system.in);

Then define a quantity to receive the input

String Input=sc.next ();

If you receive a number, you can use the following notation

int A=sc.nextint ();

 PackageCom.hanqi;ImportJava.util.Scanner; Public classTest3 { Public Static voidMain (string[] args) {//TODO Auto-generated method stubs//Console Input//Defining ScannersScanner sc=NewScanner (system.in); System.out.println ("Please enter"); //receive input, end with carriage returnString input=Sc.next (); System.out.println ("You have entered" +input); System.out.println ("Please enter a number A;"); //Receive digital inputs        intA=Sc.nextint (); System.out.println ("Please enter number B;"); intb=Sc.nextint (); intc=a+b; intd=a-b; inte=a*b; intf=a/C; System.out.println ("A and B's and is" +c); System.out.println ("A and B are the difference between" +d); System.out.println (The product of "A and B" is "+e); System.out.println ("A and B's quotient is" +f); }}
