java - 这就像一个斐波那契我无法弄清楚这个代码

Question

import java.util.*;
public class MyClass {
    public static void main(String[] args) {  
        Scanner wew = new Scanner(System.in);
        int b = 0;
        int i = 0;
        System.out.println("Enter a number of row:");
        b=wew.nextInt();
        System.out.println("Enter a number of range:");
        i=wew.nextInt();    

        for (int c = 1; c <= b; c++)
        {
            for (int g = 1; g <= i; g++){

                System.out.println(g+"");
            }
            for ( int g = c-1; g >= 1; g--)
            {
                System.out.println(g+" ");
            }
            System.out.println();
        }

    }
}

该代码仍然超出我的知识范围。这就像一个斐波那契，我知道我的输出与预期结果相差太远

预期成绩：

Please enter a number range: 4
Please enter a number rows: 4

1111 2111 3111 4111
1211 1311 1411 1511
1131 1141 1151 1161
1114 1115 1116 1117

这是你想要的 Kotlin 代码（我用这种方式开发它更容易）：

import java.util.*

fun main(args: Array<String>) {
    val input = Scanner(System.`in`)

    print("Please enter a number range: ")
    val numOfCols = input.nextInt()

    print("Please enter a number of rows: ")
    val numOfRows = input.nextInt()

    for (i in 1..numOfRows) {
        for (j in 1..numOfCols){
            for (k in 1..numOfCols){
                if (k == i) {
                    print(k+j-1)
                } else {
                    print(1)
                }
            }
            print(" ")
        }
        println("")
    }
}

这是Java等价物：

import java.util.*;

public class MyClass {
    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);

        System.out.print("Please enter a number range: ");
        int numOfCols = input.nextInt();

        System.out.print("Please enter a number of rows: ");
        int numOfRows = input.nextInt();

        for (int i = 1; i <=numOfRows; i++) {
            for (int j = 1; j <= numOfCols; j++){
                for (int k = 1; k <= numOfCols; k++){
                    if (k == i) {
                        System.out.print(k+j-1);
                    } else {
                        System.out.print(1);
                    }
                }
                System.out.print(" ");
            }
            System.out.println("");
        }
    }
}
