1、Java基础 1、为什么重写equals还要重写hashcode 简单的说就是为了保证同一个对象,保证在equals相同的情况下hashcode值必定相同,如果重写了equals而未重写hashcode方法,可能就会出现两个没有关系的对象equals相同的(因为equal都是根据对象的特征进行重写的),但hashcode确实不相同的。 为了提高程序的效率才实现了hashcode方...
25%2 equals 1 and not 0. The if statement checks whether num%2==0 is False. Since the condition is satisfied, the output says the number is odd. If it were an even number, the else condition would have been satisfied.while loop...
So simply, if we apply one more not operator in front of this, it will becomedouble notand will give the reverse value of (!expression). As seen above, (!false) will givetrue, but (!!false) will givefalse. Example for not not (!!) Operator ...

Suppose that we are given a numpy array of floats and we are creating a mask from this array where this array equals to a particular value, if yes, we do a bitwise AND (&) operation of this value with some other value.This can be done in a single-line statement as:...
