帮我正等腰三角挖空，一下想不起来
public class ccc {

public static void main(String[] args) {
a();
}

public static void a() {
System.out.println("打印正等腰三角");
int i, j;
for (i = 1; i <= 5; i++) {
for (j = 5; j > i; j--) {
System.out.print(" ");
}
for (j = 0; j < i * 2 - 1; j++) {
System.out.print("*");
}
System.out.println();
}
}
}

[解决办法]

Java code

public class ccc{        public static void main(String[] args)    {        a();    }        public static void a()    {        System.out.println("打印正等腰三角");        int i, j;        for (i = 1; i <= 5; i++)        {            for (j = 5; j > i; j--)            {                System.out.print(" ");            }            for (j = 0; j < i * 2 - 1; j++)            {                if (j == 0 || j == (i * 2 - 2) || i == 5)                {                    System.out.print("*");                }                else {                    System.out.print(" ");                }            }            System.out.println();        }    }}
