java---数组与字符串互相转换

问题：数组与字符串互相转换

解决方案：

数组==》字符串public static void join() {String[] solveIds = new String[10];Arrays.fill(solveIds, "95");System.out.println(org.apache.commons.lang.StringUtils.join(solveIds, ","));}字符串==》数组 public static String[] splitArr() {String testStr = "1@2@3@4@5";String[] solveIds = testStr.split("@");return solveIds;}
