What's wrong in my code?

package com.codegym.task.task05.task0531; import java.io.BufferedReader; import java.io.InputStreamReader; /* Improving functionality */ public class Solution { public static void main(String[] args) throws Exception { BufferedReader reader = new BufferedReader(new InputStreamReader(System.in)); int a = Integer.parseInt(reader.readLine()); int b = Integer.parseInt(reader.readLine()); int c = Integer.parseInt(reader.readLine()); int d = Integer.parseInt(reader.readLine()); int e = Integer.parseInt(reader.readLine()); int minimum = min(a, b, c, d, e); System.out.println("Minimum = " + minimum); } public static int min(int a, int b) { return a < b ? a : b; } // public static int min(int a, int b, int c, int d, int e) { // int num =Integer.MIN_VALUE; // int[] array = new int[]{a,b,c,d,e}; // for (int i=0; i<5; i++){ // if(num>array[i]){ // num=array[i]; // } // } // return num; // } public static int min(int a, int b, int c, int d, int e) { int num = 0; int[] array = new int[]{a,b,c,d,e}; for (int i=0; i<array.length-1; i++){ for(int j=i+1; j<array.length; j++){ if(array[i]<array[j]){ num=array[i];} else{ num=array[j]; } } } return num; } }
