Applets for Java recursive and recursive applications

1. Method overloading

Different types of return values are obtained by calling different functions:

Overloads of the method:
* Method name is the same
* Depending on the parameter type, the parameter type Order, the number of parameters to determine the criteria to distinguish calls
* Return value is not used as a judging condition

2. Yang Hui Triangle code:

The output of the Yang Hui Triangle is completed by a recursive relationship.

3. The judgment of palindrome string:

Code:

By using the recursive relationship, the process of judging whether a palindrome is done by invoking the function of itself.

4. Generate random numbers of code:

for (Long i = 1; i <=; i++) {//1000 random numbers
Value = 1 + (int) (Math.random () * 100); The range of random numbers is 1~100

if (i&50==0) output+= "\ n"; 50 numbers per line

5. Calculate the number of combinations:

(1) Calculation using the formula of combination number:

Use the combination number formula to calculate with n!

(2) Using recursive relations to calculate:

6. Hanoi Game:

(1) Code:

I

(2) Code:
