import java.util.Scanner;//import Scanner

Scanner input=new Scanner(System.in);//Create the scanner Obj

float numF = input.nextFloat();//Returns float
int num1 = input.nextInt(); //Returns int
byte byte1 = input.nextByte();//Returns Byte
long lg1 = input.nextLong();//Returns long
boolean b1 = input.nextBoolean();//Returns bool
double num2 = input.nextDouble();//Returns Double
String nome = input.nextLine();//Returns String

//execution is pause until you give input
