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

Usage

From source file:X.java

public static void main(String[] args) throws Exception {
    Class<?> clazz = Class.forName("X");
    X x = (X) clazz.newInstance();//from  w ww. java  2s.co m
    Field f = clazz.getField("i");
    System.out.println(f.getInt(x)); // Output: 10
    f.setInt(x, 20);
    System.out.println(f.getInt(x)); // Output: 20
    f = clazz.getField("PI");
    System.out.println(f.getDouble(null)); // Output: 3.14
    f.setDouble(x, 20);
}

From source file:Main.java

public static void main(String[] argv) throws Exception {
    Class cls = java.awt.Point.class;

    Field field = cls.getField("x");

    // Get value//from   w  w  w  .  j a  v  a 2 s .  c  o  m
    //    field.getInt(object);

    // Set value
    //  field.setInt(object, 123);

    // Get value of a static field
    field.getInt(null);

    // Set value of a static field
    field.setInt(null, 123);

}

From source file:Main.java

    if (clazzType.toString().equals("double"))
        System.out.println(field.getDouble(clazz));
