本文详细解释了Java中常用的getters和setters方法的作用、使用场景及重要性，帮助开发者更好地理解并运用这些核心概念。

简单的说就是我们常见的Bean中的get/set方法。Mutator Methods是set方法，Accessor Methods是get方法。
public class RequestParameters {
  private String id;

  // Accessor Method
  public final String getId() {
    return id;
  }

  // Mutator Method
  public final void setId(String id) {
    this.id =id;
  }
}

下面是Stack Overflow的英文原文：





An accessor method is used to return the value of a private field. It follows a naming scheme prefixing the word "get" to the start of the method name. These methods always return the same data type as their corresponding private field (e.g., String) and then simply return the value of that private field.

A mutator method is used to set a value of a private field. It follows a naming scheme prefixing the word "set" to the start of the method name. These methods do not have a return type and accept a parameter that is the same data type as their corresponding private field. The parameter is then used to set the value of that private field.
