수줍게 자바코드 올리고 갑니다......

import java.util.Scanner;
public class printfing_oxs {
 public static void main(String[] args) {
 Scanner sc = new Scanner(System.in);
 int line, i, j, k;
 while(true){
 System.out.print("input number of line : ");
 line = sc.nextInt();
 if(line > 0)
 break;
 else
 System.out.println("input number that bigger than '0'");
 }
 for(i = 0 ; i < line ; i++){
 for(j = 0 ; j < line-(i+1) ; j++){
 System.out.print("O");
 }
 for(k = 0; k < line - j ; k++){
 System.out.print("X");
 }
 System.out.println();
 }
 }
}

자바입니다

자바로 코딩
1. 입력받은 수만큼 0 으로 채움
2. String 배열로 split
3. 맨 뒤에 부터 루프 돌면서 x 로 채움

 public static void main(String[] args){
 String o = "0";
 String x = "x";
 int inputNumber = 0;
 String text = "";
 String[] textArray;
 Scanner sc = new Scanner(System.in);
 System.out.print("입력 :: ==> ");
 inputNumber = sc.nextInt();
 for(int i=0; i<inputNumber; i++){
 text += o;
 }
 textArray = text.split("");
 for(int i=textArray.length-1; i>=0; i--){
 textArray[i] = x;
 for(int j=0; j<textArray.length; j++){
 System.out.print(textArray[j]);
 }
 System.out.println("");
 }
 sc.close();
 }

 public static void main(String[] args) {
 Scanner sc = new Scanner(System.in);
 System.out.print("값 입력 : ");
 int num = sc.nextInt();
 for(int i= 1; i<=num; i++){
 for(int j=0; j<num; j++){
 if(num-i<=j) System.out.print("x");
 else System.out.print("o");
 }
 System.out.println();
 }
