The probability of error will increase. With the Builder design pattern, if you want to set a field to null, you don't need to do anything. We can also use it like this by adding the @Builder annotation.\n\n```\n@Data\n@AllArgsConstructor\n@Builder\npublic class Country {\n    private String id;\n    private String name;\n    private String nativeName;\n    private int phoneCode;\n    private String continent;\n    private String capital;\n    private String currency;\n    private List\u003cString\u003e languages;\n} \n```\n\n```\nCountry country = Country.builder()\n        .id(\"TR\")\n        .name(\"Turkey\")\n        .build();\n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fhusna-poyraz%2Fbuilder_design_pattern","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fhusna-poyraz%2Fbuilder_design_pattern","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fhusna-poyraz%2Fbuilder_design_pattern/lists"}
