Method overloading in Java

The Java language allows method overloading; the parameter count and the parameter data types of a method are part of the method identification. Thus, the same method name can be used to implement different versions of the Java method, taking different parameters:

DEFINE int2 SMALLINT, int4 INTEGER, flt FLOAT

-- Next call invokes method display(short) of the Java class
CALL myobj.display(int2)

-- Next call invokes method display(int) of the Java class
CALL myobj.display(int4)

-- Next call invokes method display(double) of the Java class
CALL myobj.display(flt)

-- Next call invokes method display(short,int) of the Java class
CALL myobj.display(int2,int4)
