Recursive programming in Java
Welcome to visit!
递归是程序设计中的一种重要概念，它指的是一个函数在其定义过程中调用自身。Java 中的递归程序设计遵循相同的思想，可以帮助简化某些复杂问题的解决方式。递归通常用于处理能够被分解为更小的子问题的问题。递归程序设计的关键在于定义递归基准条件（即终止条件）和递归规则。
Recursion is an important concept in programming, referring to a function calling itself during its definition. In Java, recursive programming follows the same principle, which can help simplify the solution of certain complex problems. Recursion is typically used to handle issues that can be broken down into smaller subproblems. The key in recursive programming lies in defining the base case (i.e., termination condition) and the recursive rule.
1.Java 中递归的基本结构
1 Java The basic structure of recursion
A recursive program consists of two parts:
递归基准条件：是递归结束的条件。没有基准条件或者基准条件错误会导致递归无限进行下去，造成栈溢出（Stack Overflow）。
Recursive base condition: is the condition for the end of recursion. Without a base condition or an incorrect base condition, the recursion will continue indefinitely, resulting in stack overflow (Stack Overflow).
递归调用：将问题分解成更小的子问题，逐步缩小问题的规模，直到达到基准条件。
Recursive call: Break down the problem into smaller subproblems and gradually reduce the size of the problem until the base condition is reached.
2.递归的工作原理
2. How recursion works
当一个递归函数被调用时，程序会先执行当前函数的代码，然后在遇到递归调用时，会进入新的函数调用栈，直到达到基准条件。如果没有基准条件，递归将无法停止，程序会进入无限循环。
When a recursive function is called, the program executes the code of the current function first, and then enters a new function call stack when it encounters a recursive call until the base condition is reached. Without a base condition, the recursion will not stop and the program will enter an infinite loop.
3.递归实现
3. Recursion implementation
public class Factorial {
// 递归函数计算阶乘
public static int factorial(int n) {
// 递归基准条件
if (n == 0) {
return 1;
}
// 递归调用
return n * factorial(n - 1);
}
public static void main(String args) {
int number = 5;
System.out.println("Factorial of " + number + " is: " + factorial(number));
}
}
4.递归的优缺点
4. Advantages and disadvantages of recursion
优点：
merit:
简化了代码，能使某些问题的解法更加直观。
Simplifies the code and makes the solution to some problems more intuitive.
适用于那些可以被分解为相似子问题的问题，比如树形结构、图遍历、动态规划等。
It is suitable for problems that can be decomposed into similar subproblems, such as tree structure, graph traversal, dynamic programming, etc.
缺点：
shortcoming:
递归调用会占用栈空间，如果递归太深，可能会导致栈溢出（StackOverflowError）。
Recursive calls take up stack space, and if the recursion is too deep, it may cause a stack overflow (StackOverflowError).
调试和理解递归程序可能较为困难，尤其是当递归的调用层数较深时。
Debugging and understanding recursive programs can be difficult, especially when the depth of recursive calls is deep.
总结来说，Java 中的递归程序设计是通过函数自身调用来解决问题的，合适的基准条件和合理的递归步骤可以帮助解决复杂的问题。
In summary, recursive programming in Java solves problems by calling the function itself. Appropriate base conditions and reasonable recursive steps can help solve complex problems.
