如何在我已经定义的类中实现构建器

public class MyClass {
    private final String property1;
    private final int property2;
    // 其他属性...

    private MyClass(Builder builder) {
        this.property1 = builder.property1;
        this.property2 = builder.property2;
        // 设置其他属性...
    }

    public static class Builder {
        private String property1;
        private int property2;
        // 其他属性...

        public Builder property1(String value) {
            this.property1 = value;
            return this;
        }

        public Builder property2(int value) {
            this.property2 = value;
            return this;
        }

        // 设置其他属性的setter方法...

        public MyClass build() {
            return new MyClass(this);
        }
    }
}

MyClass myObject = new MyClass.Builder()
    .property1("value1")
    .property2(2)
    // 设置其他属性...
    .build();
