Answer / chandrarekha
all the primitive or the simple datatypes(int,float,boolean
etc) are passed as call by value whereas the abstract
datatypes(class objects) are by call by reference.....
for example...
class classA
{
String name;
}
class classB
{
classA a=new classA();
a.name="java";
call(a);//a is an object of classA
void call(classA x)
{
x.name="JAVA";
}
public static void main()
{
......
this is call by reference...
