The
java.lang.Object class is the ultimate superclass of all
objects If a class does not explicitly extend a class, then the compiler
assumes it extends java.lang.Object.
There is one exception. Guesses?
The Methods of java.lang.Object
java.lang.Object provides a number of methods
that are common to all objects. toString() is the most common
such method. Since the default toString() method only
produces the name of the class, you should override it in all classes you
define.
public Object()
public final Class getClass()
public int hashCode()
public boolean equals(Object obj)
protected Object clone() throws
CloneNotSupportedException
public String toString()
public final void notify()
public final void notifyAll()
public final void wait(long timeout) throws
InterruptedException
public final void wait(long timeout, int nanos)
