How to force a class to be initialised? [closed]

Answer 1

You can use the following code to force initialization of a class:

//... Foo.class ...          //OLD CODE
... forceInit(Foo.class) ... //NEW CODE

/**
 * Forces the initialization of the class pertaining to 
 * the specified Class object. 
 * This method does nothing if the class is already
 * initialized prior to invocation.
 *
 * @param klass the class for which to force initialization
 * @return klass

 */
public static  Class forceInit(Class klass) {
    try {
        Class.forName(klass.getName(), true, klass.getClassLoader());
    } catch (ClassNotFoundException e) {
        throw new AssertionError(e);  // Can't happen
    }
    return klass;
}
