Using a custom Java class
The following code provides a more complex custom class than in the example
on page 1137. The Example class manipulates integer, float, array, Boolean, and Example object types.
The Example class
The following Java code defines the Example class. The Java class Example has one public integer member,
. Its constructor initializes
mPublicInt
methods:
Method

to 0 or an integer argument. The class has the following public
mPublicInt
Description
Reverses the order of a string.
