I was solving a leet code problem using java and the problem number is “1832. Check if the sentence is pangram”. Before watching the solutions on youtube, I want to try my own code with my own logic in a brute force manner without optimisation. I am Sorry if all this seems silly I am still in the learning phase. In leetcode platform, other online java compilers and IDE’s are showing the same errors.

My Code on the leetcode platform is:

class Solution {
    public static boolean checkIfPangram(String sentence) {
        char[] arr = new char[26];
        char[] arr1 = new char[sentence.length()];
        int count=0;
        arr={"a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z"};
        for(int i=0;i<arr1.length;i++){
            arr1[i]=sentence.charAt(i);
        }
        for(int i=0;i<26;i++){
            for(int j=0;j<arr1.length;j++){
                if(arr[i]==arr1[j]){
                    count++;
                    break;
                }
            }
        }
        return (count==26);
    }
}

Line 6: error: illegal start of expression
arr = {‘a’,’b’,’c’,’d’,’e’,’f’,’g’,’h’,’i’,’j’,’k’,’l’,’m’,’n’,’o’,’p’,’q’,’r’,’s’,’t’,’u’,’v’,’w’,’x’,’y’,’z’};

I tried the same code in IDE:

import java.util.*;
class Main {
    public static void main(String[] args){
        String a ="thequickbrownfoxjumpsoverthelazydog";
        System.out.println(checkIfPangram(a));
    }
    public static boolean checkIfPangram(String sentence) {
        char[] arr = new char[26];
        char[] arr1 = new char[sentence.length()];
        int count=0;
        arr={"a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z"};
        for(int i=0;i<arr1.length;i++){
            arr1[i]=sentence.charAt(i);
        }
        for(int i=0;i<26;i++){
            for(int j=0;j<arr1.length;j++){
                if(arr[i]==arr1[j]){
                    count++;
                    break;
                }
            }
        }
        return (count==26);
    }

}

But still the same error was shown. Kindly explain why is it showing so!
