ভাই খুব বিপদে ছিলাম জাভা নিয়ে
সেমিস্টার প্রায় শেষ ।এখন মাত্র ১০ দিনের মত বাকি।এত তারাতারি কিভাবে কি করব বুঝতেসিলাম না।আপনার ভিডিওগুলো দেখে মনে হচ্ছে আল্লাহর রহমতে অনেক কিছুই পারব
ধন্যবাদ ভাই

Take an array of 10 elements. Split it into middle and store the elements in two dfferent arrays. please explain this problem please sir

What's the shortcut for creating for loops brother? and love your videos. Thank you!

[yasminsultanaemu]

.ArrayIndexOutOfBoundsException, i coded as same as you did but this exception throws every time. can you tell me how to solve? I've searched everywhere but can't find the solution. Here is the code where i can't take array elements input:
//import java.lang.reflect.Array;
import java.util.Scanner;

public class Main {
public static void main(String[] args) {
System.out.println("Hello world!");
int [][]num=new int[2][3];
Scanner in=new Scanner(System.in);
int i, j;
for(i=0; i<2; i++){
for( j=0; j<3; j++){
num[2][3]=in.nextInt();
}

}
}
}
