Invoking method with name pattern

I need to call some functions generated by some libs. I will need to call fucntion1, function2, ..., function10 one by one. Instead of writing them all out on the code, is there any clever way to code it?

You could also use the Expression class from java.beans package

http://download.oracle.com/javase/6/docs/api/index.html?java/beans/package-summary.html

construct a expression object.

Expression(Object target,String methodName,Object[] arguments)

and then on the expression object you can use getValue()

Cheers!

You could use reflection.

Some some = new Some();

for (int i = 1; i <= 10; i++) {
    some.getClass().getMethod("function" + i).invoke(some);
}
