In most of my programs in which I have to take input from console . I have used Scanner object .
The below program tells how to use it.
public class inputoutput{
public static void main(String args[]){
System.out.println("enter any number");
Scanner input = new Scanner(System.In);
int x = input.nextInt();
}
}
now Scanner class provides you with lot of methods to read int, short, strings and other things .
A basic google will solve your problems.
I have not till yet tried to make any java program which reads from file. once done will blog it.
Regarding the Output .
System.out.println(): will work smoothly .
To type some explanation and then you variable
System.out.println("this is your answer" + var_name); + is something like ',' of C
To print multiple variables, see sample program
public class io {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
int a= 12;
int b=34;
String c = "leo";
System.out.println("my name and number is " + c + a +" " + b);
}
}
Unlinke C, there is typefdef format symbol needed to be put. In case you need to output Hexa value of int , there will be some method surely, I have not still explored that .
