1)Lock是一个接口,而synchronized是Java中的关键字,synchronized是内置的语言实现; 2)synchronized在发生异常时,会自动释放线程占有的锁,因此不会导致死锁现象发生;而Lock在发生异常时,如果没有主动通过unLock()去释放锁,则很可能造成死锁现象,因此使用Lock时需要在finally块中释放锁; 3)Lock可以
Scientific notation is the way that scientists easily handle very large numbers or very small numbers. The notation matches the regular expression [+-][1-9].[0-9]+E[+-][0-9]+ which means that the integer portion has exactly one digit, there is at least one digit in the fractional po...
letnumberInScientificNotation=6.0221e23;// Avogadro's numberconsole.log(numberInScientificNotation); Output: 6.0221e+23 JavaScript’s default behavior is to convert any floating-point value with at least six trailing zeros into an e-notation. This simplifies the representation and facilitates the effi...
