有人可以帮助我纠正一下这个Java Pangram程序中的错误吗

我的Java代码有问题，但我无法检测到。我错了一个代码来检查pangram。Eveything看起来很麻烦，但是我的代码无法编译和运行。这是我得到的错误。线程“主”中的异常java.lang.ArrayIndexOutOfBoundsException：42 at pangram.Pangram.main（Pangram.java:29）

package pangram;

import java.util.Scanner;

public class Pangram {
    public static void main(String[] args) {
        //take input from the user
        Scanner scan = new Scanner(System.in);
        System.out.println("Please enter a word or sentence:");
        String sentence=scan.nextLine();
        //String sentence = "the quick brown fox jumps over lazy dog";
        String sentence1=sentence.replace(" ", "");
        //extract data from the object and place in an array x
        char x[]=sentence1.toCharArray();
        int size=x.length;

        //initialize another array with zeros to fill the 26 positions of A-Z
        int y[]={0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0};

        //loop through the array using while loop
        int i;
        for(i=0;i<=size;i++){
            int indexOfLetter=x[i]-65;
            //if you find the letter matching, replace 0 with 1 at that postion
            y[indexOfLetter]=1;
            ++i;
        }
        //here check if its indeed a pangram
        i=0;
        while(i!=26){ //26 is the number of letters in alphabet A-Z
            if(y[i]==1){
                i++;
            }else{
                System.out.println("NO");
            }

        }
        System.out.println("YES");

    }
