1. SCJP
2. Java Source And Data Type
3. float

float and double use 32 and 64 bits, respectively. 
Float literals end in F or f, double literals end in a digit or D or d.
Floating-point numbers are implicitly doubles (64 bits).

public class MainClass{
  public static void main(String[] argv){
    double myDouble;
    float myFloat;

    myDouble  = 1.1;
    myFloat  = 1.2F; // F stands for float 
  }

}
