Question

What is the output of the following code fragment:

int[] ar = {2, 4, 6, 8 };
System.out.println( ar[0] + "" "" + ar[1] );

Answer 1

The code fragment is Java and prints the first two elements of the integer array 'ar'. The output will be '2 4', representing the values at indexes 0 and 1, respectively.

Step-by-step explanation:

The provided code fragment is written in Java and is concerned with array indexing and output. Specifically, the code initializes an array ar with integers and prints elements via their indexes.

When the System.out.println method is called, it outputs the values of ar[0] and ar[1] concatenated, with a space between them. The output will be the first and second elements of the array ar separated by a space.

The code fragment is Java and prints the first two elements of the integer array 'ar'. The output will be '2 4', representing the values at indexes 0 and 1, respectively.

Given the array int[] ar = {2, 4, 6, 8 }, the output will be: "2 4". Here, ar[0] is 2 and ar[1] is 4, hence the printed result is these two numbers with a space in between.
