You can use Scanner class. It is have a method nextFloat() which allow you to input float value.

import java.util.*;
class  ScannerExample
{
    public static void main(String[] args) 
    {
        Scanner input=new Scanner(System.in);
        System.out.print("Enter float value: ");
        float f=input.nextFloat();
        System.out.println(f);
    }
}
