和C 类似,Java 提供了丰富的快捷运算。这些快捷运算使编码更方便,同时也使得代码更 容易阅读,但是有时可能使代码阅读起来更困难。 递增和递减运算是两种相当不错的快捷运算(常称作“自动递增”和“自动递减”运算)。其中, 递减操作符是“--”,意为“减少一个单位”;递增操作符是“++”,意为“增加一个单位”...
Strange Behavior of Java Postfix Operators Sometimes you may see the postfix form of increment or decrement operator behaving strangely. For an example, take look at the following piece of code: intx=1;x=x++;System.out.println("x : "+x);//will print x : 1 ...
Example: Using Decrement in Expressions Following code demonstrates the postfix decrement operator used in an expression. The variable 'a' is initialized to 5. In the expression b = a-- + 3, a is first used as 5, so 5 + 3 = 8 is assigned to 'b'. After the expression is evaluated,...
This method was added in java 9. getAndIncrement()Increments the present value by 1 and returns theoldervalue. getAndDecrement()Decreases the present value by 1 ad returns theoldervalue. getAndAdd(int value)Adds the given value to the present value and returns theoldervalue. ...
decrement(): java public void decrement() { if (counterValue > 0) { counterValue--; } } 该方法在counterValue大于0时将其值减1,以避免负值。 reset(): java public void reset() { counterValue = 0; } 该方法将counterValue的值重置为0。 获取当前计数值的方法: java public int getCoun...

Java Increment and Decrement OperatorsThere are 2 Increment or decrement operators -> ++ and --. These two operators are unique in that they can be written both before the operand they are applied to, called prefix increment/decrement, or after, called postfix increment/decrement. The meaning ...
