JAVA筆試題

由於朋友去面試遇到“JAVA 輸出左右上下對稱的圖形” 這道題，特記下以便自己遇到時也能做！哈哈！

public class PrintSymmetrical {

	public static void main(String[] args) {

		for (int i = 0; i <= 3; i++) {
			for (int j = 0; j <= 2 - i; j++) {
				System.out.print(" ");
			}
			for (int k = 0; k <= 2 * i; k++) {
				System.out.print("*");
			}
			System.out.println("");
		}

		for (int i = 0; i <= 2; i++) {
			for (int j = 0; j <= i; j++) {
				System.out.print(" ");
			}
			for (int k = 0; k <= 4 - 2*i; k++) {
				System.out.print("*");
			}
			System.out.println("");
		}

		System.out.println("+++++++++++++這是分割線+++++++++++++");

		int count = 1; 

		for (int i = 0; i <= 3; i++) {
			for (int j = 0; j <= 2 - i; j++) {
				System.out.print(" ");
			}
			for (int k = 0; k <= 2 * i; k++) {
				System.out.print(count++);
			}
			count = 1;
			System.out.println("");
		}


		for (int i = 0; i <= 2; i++) {
			for (int j = 0; j <= i; j++) {
				System.out.print(" ");
			}
			for (int k = 0; k <= 4 - 2*i; k++) {
				System.out.print(count++);
			}
			count = 1;
			System.out.println("");
		}

	}

}

輸出如下：
