JAVA做等腰三角形

Question

不知道怎么让它呈现等腰
package com.czie;

import java.util.Scanner;

public class MyMain {

/**
 * @param args
 */
public static void main(String[] args) {
    // TODO Auto-generated method stub
    Scanner scanner = new Scanner(System.in);
    System.out.println("输入行数。。。。");
    int line = scanner.nextInt();

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

}

}

import java.util.Scanner;

public class MyMain {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.println("输入行数：");
        int line = scanner.nextInt();

        for (int i = 0; i < line; i++) {
            // 打印左侧的空格
            for (int j = 1; j <= line - i; j++) {
                System.out.print(" ");
            }
            // 打印等腰三角形部分
            for (int k = 0; k < i * 2 + 1; k++) {
                System.out.print("m");
            }
            System.out.println("");
        }
    }
}
