Gets the value of a static or instance field of type float or of another primitive type convertible to type float via a widening conversion.

Usage

From source file:MyClass.java

public static void main(String[] args) throws Exception {
    Class<?> clazz = Class.forName("MyClass");
    MyClass x = (MyClass) clazz.newInstance();

    Field f = clazz.getField("i");
    System.out.println(f.getFloat(x));

    f.setFloat(x, 9.99F);//from  w  ww.j  a v a  2 s  .co m
    System.out.println(f.getFloat(x));

}
