java方法思路

//根据行、列、字符打印对应行数的字符
//比如：行：4，列：4，字符#，则打印相应的效果

1.方法的返回类型
2.方法的名字
3.方法的形参
4.方法体，判断

import java.util.Scanner;

public class 类名 {
	public static void main(String[] arg) {
		Scanner sc = new Scanner(System.in);
		int n = sc.nextInt();
		
		print(n);
	}
	
	public static void print(int a) {
	
		for (int i = 0; i < a; i++) {
			for (int j = 0; j < a; j++) {
				System.out.print("#");
			}
			System.out.println();
		}
	}
}

import java.util.Scanner;

public class practice2 {
	public static void main(String[] arg) {
		Scanner sc = new Scanner(System.in);
		int a = sc.nextInt();
		int b = sc.nextInt();
		print(a,b,'#');
	}
	
	public static void print(int row, int col, char a) {
		
		for (int i = 0; i < row; i++) {
			for (int j = 0; j < col; j++) {
				System.out.print(a);
			}
			System.out.println();
		}
	}
}
