package javatext1Pro;

{class javatext1 public
public static void main (String [] args) {
// output a floating point number, a special bit, there must be used in a digital behind f represents
a float f = 1.1f;
System.out.println ( "f =" + F);
// float obtaining maximum, minimum
float max = Float.MAX_VALUE;
float min = Float.MIN_VALUE;
System.out.println ( "max =" + max);
System.out.println ( "= min" min +);

}
}
