1) Save the Test Program above as SerialTest.java
2) javac -Xlint:all SerialTest.java

 Output from javac:

    SerialTest.java:1: cannot find symbol
    symbol: class Typo
    class SerialTest extends Typo { }
                             ^
    SerialTest.java:1: warning: [serial] serializable class SerialTest
