如何将“_INC”(字符串)附加到List中的每个元素的末尾？
如何将“_INC”(字符串)附加到List中的每个元素的末尾？
提问于 2018-12-04 05:56:32
我想将"_INC“附加到列表中的每个元素。列表内容如下所示：
public final static List<String> PROVIDERS = Arrays.asList("asco_genes", "pubmed_oa_genes", "wiley_journals_genes", "mms_genes", "elsevier_genes", "medline_genes",
"asco_drugs", "pubmed_oa_drugs", "wiley_journals_drugs", "mms_drugs", "elsevier_drugs", "medline_drugs", "aaas_genes", "aaas_drugs", "aacr_genes","aacr_drugs",
"springer_nature_genes", "springer_nature_drugs");在编程逻辑之后，列表应该如下所示：
public final static List<String> PROVIDERS = Arrays.asList("asco_genes_INC", "pubmed_oa_genes_INC", "wiley_journals_genes_INC", "mms_genes_INC", "elsevier_genes_INC", "medline_genes_INC",
"asco_drugs_INC", "pubmed_oa_drugs_INC", "wiley_journals_drugs_INC", "mms_drugs_INC", "elsevier_drugs_INC", "medline_drugs_INC", "aaas_genes_INC", "aaas_drugs_INC", "aacr_genes_INC","aacr_drugs_INC",
"springer_nature_genes_INC", "springer_nature_drugs_INC");我已经研究过使用字符串构建器和使用字符数组来完成任务，但它们看起来有点复杂。我想知道java是否有任何预定义的库可以让这件事变得更容易。

Java 8+您可以创建一个stream并添加"_INC"，然后将其收集到List中
List<String> list = Stream.of("asco_genes", "pubmed_oa_genes", "wiley_journals_genes", "mms_genes", "elsevier_genes", "medline_genes",
"asco_drugs", "pubmed_oa_drugs", "wiley_journals_drugs", "mms_drugs", "elsevier_drugs", "medline_drugs", "aaas_genes", "aaas_drugs", "aacr_genes","aacr_drugs",
"springer_nature_genes", "springer_nature_drugs")
.map(e -> e + "_INC")
.collect(Collectors.toList());这会产生：
mms_genes_INC
elsevier_genes_INC
medline_genes_INC
asco_drugs_INC
pubmed_oa_drugs_INC
wiley_journals_drugs_INC
mms_drugs_INC
elsevier_drugs_INC
medline_drugs_INC
aaas_genes_INC
aaas_drugs_INC
aacr_genes_INC
aacr_drugs_INC
springer_nature_genes_INC
