Typescript:实现具有3个不同签名的接口的方法？

interface MyInterface {
  method1(arg1: string): void;
  method2(arg1: number, arg2: boolean): string;
  method3(): number[];
}

class MyClass implements MyInterface {
  method1(arg1: string): void {
    // 实现method1的逻辑
  }

  method2(arg1: number, arg2: boolean): string {
    // 实现method2的逻辑
    return "";
  }

  method3(): number[] {
    // 实现method3的逻辑
    return [];
  }
}

const myObj = new MyClass();
myObj.method1("argument");
const result = myObj.method2(123, true);
const numbers = myObj.method3();
