如何生成自定义Java对象的多个元组或字符串组合

public class CustomObject {
    private String name;
    private int age;

    public CustomObject(String name, int age) {
        this.name = name;
        this.age = age;
    }
}

// 创建对象
CustomObject obj1 = new CustomObject("John", 25);
CustomObject obj2 = new CustomObject("Alice", 30);

public class CustomObject {
    private String name;
    private int age;

    private CustomObject() {}

    public static class Builder {
        private CustomObject obj;

        public Builder() {
            obj = new CustomObject();
        }

        public Builder setName(String name) {
            obj.name = name;
            return this;
        }

        public Builder setAge(int age) {
            obj.age = age;
            return this;
        }

        public CustomObject build() {
            return obj;
        }
    }
}

// 创建对象
CustomObject obj1 = new CustomObject.Builder()
                        .setName("John")
                        .setAge(25)
                        .build();
CustomObject obj2 = new CustomObject.Builder()
                        .setName("Alice")
                        .setAge(30)
                        .build();

public class CustomObjectFactory {
    public static CustomObject createObjectWithName(String name) {
        CustomObject obj = new CustomObject();
        obj.setName(name);
        return obj;
    }

    public static CustomObject createObjectWithAge(int age) {
        CustomObject obj = new CustomObject();
        obj.setAge(age);
        return obj;
    }
}

// 创建对象
CustomObject obj1 = CustomObjectFactory.createObjectWithName("John");
CustomObject obj2 = CustomObjectFactory.createObjectWithAge(25);
