Usage

From source file:Main.java

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

    Field[] fields = cls.getFields();
    for (int i = 0; i < fields.length; i++) {
        Class type = fields[i].getType();
        System.out.println(fields[i]);
    }/*from  w  w w  . j  a va 2s.c om*/
}

From source file:Spy.java
