运用方法:DBCollection对象方法中的 distinct() 语句: 语句结构:distinct(key,[query]) key字符串,指定获取哪个字段的不同值;query:包含标准查询选项的对象,指定了要从哪个文档中获取不同的字段值 举例说明: 如下是 inventory 集合的数据 { "_id": 1, "dept": "A", "item": { "sku": "111", "color"...
||(OR)多个条件只要有一个为 true 结果就为 true !(NOT)条件如果为 true,加上“!”就为 false,否则,反之。 来看一个例子: 代码语言:javascript 复制 public class LogicalOperator { public static void main(String[] args) { int a=10; int b=5; ...
In the JDK, java.text.MessageFormat now has an implementation limit for the ArgumentIndex pattern element. The hard limit for the value is 10,000. If an ArgumentIndex value is equal to or exceeds the upper limit, an IllegalArgumentException will now be thrown by MessageFormats constructors ...

The output of the program is shown here: b = false b = true Ternary Operator Java includes a special ternary (three-way) operator that can replace certain types of if-then-else statement. Java包含一个特殊的运算符(三元运算符),可以替代语句if-then-else类型。
