轻松设置"this"变量？

class Example {
  constructor(value) {
    this.value = value;
  }

  printValue() {
    console.log(this.value);
  }
}

const exampleInstance = new Example(42);
exampleInstance.printValue(); // 输出 42

public class Example {
  private int value;

  public Example(int value) {
    this.value = value;
  }

  public void printValue() {
    System.out.println(this.value);
  }
}

Example exampleInstance = new Example(42);
exampleInstance.printValue(); // 输出 42

public class Example {
  private int value;

  public Example(int value) {
    this.value = value;
  }

  public void PrintValue() {
    Console.WriteLine(this.value);
  }
}

Example exampleInstance = new Example(42);
exampleInstance.PrintValue(); // 输出 42

class Example:
    def __init__(self, value):
        self.value = value

    def print_value(self):
        print(self.value)

example_instance = Example(42)
example_instance.print_value()  # 输出 42
