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;
	}
