Answer 1

import java.util.Arrays;

public class Program {
public static void main(String[] args) {
int[] marks = new int[3];
marks[0] = 89;
marks[1] = 90;
marks[2] = 78;

// Sorting the array
Arrays.sort(marks);

// Printing the second element of the sorted array
System.out.println(marks[1]);
}
}
this will be its correct code

Answer 2

an array can be declared like this:
int [] marks = new int[3];

if you want to print the first element, remove the "" from the output

Answer 3

I haven't code for Java for a while and forget how to create array.
After reviewing my notes, I also found another you made.

Instead of:
int marks[0] = 89;

It should be:
marks[0] = 89;

You already declared an integer array, so you don't need to assign an array member and state that it is an integer again.

Answer 4

Okk Thanku now its done I will try to be more clear with these syntax

Answer 5

Lisa its still not done

Answer 6

carefully compare my example and your line 7. which part is missing in your code?

Answer 7

Aditi Chand

look at Lisa's reply carefully.

this
⬇️
int[] marks = new int[3];

your code:
int marks = new int[3];

type int is not the same as type int[]. one is integer, the other is integer array

Answer 8

Can you just do it and share it please

Answer 9

don't be lazy... if you can't see the mistake now, you should redo the lesson. Don't build on shaky foundations.

Answer 10

Wong Hei Ming those new errors must have been added afterwards. They were not there when I looked at the code.
Now there are more mistakes in the code.
Please redo the lesson. The basics are very important. Do not guess the correct syntax.
