🔍Prime Number 추출하기

int[] arr = { 0,1,2,3,4,5,6,7,8,9 };

✏️Solution

int[] arr = { 0,1,2,3,4,5,6,7,8,9 };
		for(int index = 0; index < arr.length; index++) {
			int number = arr[index];
			
			switch(number) {
				case 0,1 -> {;;}
				default -> {
					boolean isPrimeNumber = true;
					
					for(int s = 2; s < number; s++) {
						if(number % s == 0) {
							isPrimeNumber = false;
							break;
							} 
						}
					if(isPrimeNumber) {
						System.out.println(number);
					}
				} // default
			} // switch
		}// for
