java黑皮书课后习题：10.18求大于long.maxValue的五个素数

public static void main(String[] args) {
	
	
	BigDecimal lmv = new BigDecimal(Long.MAX_VALUE);
	BigDecimal num = BigDecimal.ONE;
	int count = 0;
	lmv.add(num);
	for(;count < 5;lmv = lmv.add(num)) {
		
		if(isPrime(lmv)) {
			System.out.println("The Prime number is " + lmv);
			count++;
		}
	}
}


public static boolean isPrime(BigDecimal num) {
	BigDecimal one = BigDecimal.ONE;
	BigDecimal two = new BigDecimal("2");
	BigDecimal temp = one.add(one);
	for(;temp.compareTo(num.divide(two)) <= 0;temp = temp.add(one)) {
		BigDecimal tmp = num.remainder(temp);
		//System.out.println(temp);
		if(temp.equals(BigDecimal.ZERO))
			return false;
	}
	return true;
