User input in apex class using developer console

Question

as am new to Apex programming. Am learning the apex using developer console and want to take the user input using the execution window.I want to take user input for array with 25 elements. How can we fulfill this ? Can there be any other method except passing as argument in function?

Answer 1

You can easily define methods or classes that take input.

public static Integer double(Integer x) { return 2 * x; }
public class MyClass
{
    public void doStuff(String input)
    {
        // logic here
    }
}

system.debug(double(21));
MyClass instance = new MyClass();
instance.doStuff('Some input');

You can specify up to 32 different parameters of any type.

public static void doStuff(List<Integer> dataType1, List<String> dataType2)
{
    // do stuff
}
