Question

我在我的项目中使用最新的HSQLDB 2.3.2但是几天后DB工作不正常。根本原因是

java.sql.SQLException: java.lang.NoClassDefFoundError: org/hsqldb/lib/LongValueHashMap

我检查了JAR，这个类在给定的路径上。什么可能是错的？

现在，类路径上可能还有较旧版本的HSQLDB jar。

您可以通过静态引用来检查数据库版本的function unite() { var args = arguments; var hash = {}; //why do we have to declare an object? var arr = []; for (var i = 0; i < args.length; i++) { for (var j = 0; j < args[i].length; j++) { if (hash[args[i][j]] !== true) { //this part onwards gets confusing arr[arr.length] = args[i][j]; //i dont understand how arr.length increase for every loop hash[args[i][j]] = true; } } } return arr; } unite([1, 3, 2], [1, [5]], [2, [4]]);字段。
