Usage

From source file:Main.java

public static void main(String[] args) {
    Rectangle r = new Rectangle(100, 325);
    Class c = r.getClass();//from   ww w .  j ava 2 s.  c o  m
    try {
        Field heightField = c.getField("height");
        heightField.setInt(r, 1000);
        Integer heightValue = (Integer) heightField.get(r);
        System.out.println("Height: " + heightValue.toString());
    } catch (Exception e) {
        System.out.println(e);
    }
}

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 w  w  .  java  2 s  .  c o 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 {

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

    // Get value//w  w w .  j  a va  2  s .com
    //    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);
