Hello, I need a help with my java lab homework:

Recursion

-Add all 3 recursive recursive methods from this presentation

-Write a method that computes the value of ln(N!)

-HINT: one liner

-3 test cases for each method (No Scanner!)

//////////////////////////////////////////////////////////////

Example of recrusion method:

public int method(int n) {

if(1 == n) {

return n;

}

return method(n-1);

}
