    [JAVA]16.오름차순 별그리기
     
     
    1.절차 만들기
     
     
     
     
     
    2별을 출력해본다.
     
    public class pra01 {
    public static void main(String[] args) {
        System.out.print("*");
    }
}
     
    3하드코딩해서 별 한 줄을 만든다:
     
    public class pra01 {
    public static void main(String[] args) {
        System.out.print("*");
        System.out.println("");

        System.out.print("*");
        System.out.println("");

        System.out.print("*");
        System.out.println("");

        System.out.print("*");
        System.out.println("");

        System.out.print("*");
        System.out.println("");

        System.out.print("*");
        System.out.println("");

        System.out.print("*");
        System.out.println("");

        System.out.print("*");
        System.out.println("");

        System.out.print("*");
        System.out.println("");

    }
}
     
    4하드코딩해서 별 오름차순으로 만든다:
     
    public class pra01 {
    public static void main(String[] args) {
        System.out.print("*");
        System.out.println("");

        System.out.print("*");
        System.out.print("*");
        System.out.println("");

        System.out.print("*");
        System.out.print("*");
        System.out.print("*");
        System.out.println("");

        System.out.print("*");
        System.out.print("*");
        System.out.print("*");
        System.out.print("*");
        System.out.println("");

        System.out.print("*");
        System.out.print("*");
        System.out.print("*");
        System.out.print("*");
        System.out.print("*");
        System.out.println("");

        System.out.print("*");
        System.out.print("*");
        System.out.print("*");
        System.out.print("*");
        System.out.print("*");
        System.out.print("*");
        System.out.println("");

        System.out.print("*");
        System.out.print("*");
        System.out.print("*");
        System.out.print("*");
        System.out.print("*");
        System.out.print("*");
        System.out.print("*");
        System.out.println("");

        System.out.print("*");
        System.out.print("*");
        System.out.print("*");
        System.out.print("*");
        System.out.print("*");
        System.out.print("*");
        System.out.print("*");
        System.out.print("*");
        System.out.println("");

        System.out.print("*");
        System.out.print("*");
        System.out.print("*");
        System.out.print("*");
        System.out.print("*");
        System.out.print("*");
        System.out.print("*");
        System.out.print("*");
        System.out.print("*");
        System.out.println("");

    }
}
     
     
     
    5공통 모듈을 만든다:
    public class pra01 {
    public static void main(String[] args) {

        int b = 0;
        
        b++;
        for (int a = 1; a <= b; a++) {
            System.out.print("*");
        }
        System.out.println("");
        
        b++;
        for (int a = 1; a <= b; a++) {
            System.out.print("*");
        }
        System.out.println("");
        
        b++;
        for (int a = 1; a <= b; a++) {
            System.out.print("*");
        }
        System.out.println("");
        
        b++;
        for (int a = 1; a <= b; a++) {
            System.out.print("*");
        }
        System.out.println("");
        
        b++;
        for (int a = 1; a <= b; a++) {
            System.out.print("*");
        }
        System.out.println("");
        b++;

        for (int a = 1; a <= b; a++) {
            System.out.print("*");
        }
        System.out.println("");
        
        b++;
        for (int a = 1; a <= b; a++) {
            System.out.print("*");
        }
        System.out.println("");
        b++;

        for (int a = 1; a <= b; a++) {
            System.out.print("*");
        }
        System.out.println("");
        
        b++;
        for (int a = 1; a <= b; a++) {
            System.out.print("*");
        }
        System.out.println("");
        
        b++;
    }
}
     
    6.불필요한 것을 반복문으로 올린다:
     
    public class pra01 {
    public static void main(String[] args) {

        for (int b = 1; b < 10; b++) {
            for (int a = 1; a <= b; a++) {
                System.out.print("*");
            }
            System.out.println("");

        }

    }
