Скачать или смотреть Java Programming[4] - Numeric Datatype and Operations

In this video we have discussed the numeric data type in java, type casting, literals and numeric operators.

Here is the code for our first program in the discussion:

import java.util.Scanner;
public class NumericTypeInput
{
public static void main(String ec[])
{
byte varByte;
short varShort;
int varInt;
long varLong;
float varFloat;
double varDouble;

Scanner input = new Scanner(System.in);
System.out.print("Enter a byte value: ");
varByte = input.nextByte();

System.out.print("Enter a short value: ");
varShort = input.nextShort();

System.out.print("Enter an int value: ");
varInt = input.nextInt();

System.out.print("Enter a long value: ");
varLong = input.nextLong();

System.out.print("Enter a float value: ");
varFloat = input.nextFloat();

System.out.print("Enter a float value: ");
varDouble = input.nextDouble();

System.out.println("Byte = " + varByte
"\n Short = " + varShort + "\n Int = "
varInt + "\n Long = " + varLong
"\n Float = " + varFloat
"\n Double = "+varDouble);
}
}
