Check Prime Number Example in Java - This program will read an integer number and check whether given number is Prime or Not, in this program we will divide number from 2 to number/2, if number divide by any number then number will not be prime number....
System.out.println("Prime check started for number: "+ crunchifyNumber); if(crunchifyNumber ==1){ return"1 is not a Prime number..."; } // Loop starts from 2 for(inti =2; i<= crunchifyNumber /2; i++){ if(crunchifyNumber % i ==0){ returncrunchifyNumber +" ==> ...

System.out.println(isPrime(n)?"prime":"not prime"); } } 解释: // certainty - 这一措施的调用者能容忍的不确定性:如果调用返回true,// 则此BigInteger是素数超过概率(1 - 1/2确定性)。此方法的执行时间正比于该参数的值。publicbooleanisProbablePrime(intcertainty){if(certainty <=0)returntrue;BigInte...
hashCode() Returns the hash code for this BigInteger. int intValue() Converts this BigInteger to an int. boolean isProbablePrime(int certainty) Returns true if this BigInteger is probably prime, false if it’s definitely composite. long longValue() Converts this BigInteger to a long. BigInteger...
