Question

I am teaching myself Java and am getting this error when I run code in my scrap book in Eclipse:

Syntax error, insert "AssignmentOperator Expression" to complete Expression

Here is my scrap book:

Sorter sorter = new Sorter();
int[] nums = {5, 6, 7, 8, 1, 2, 3, 4};
sorter.selectionSort(nums);
nums;

Here is the Sorter class.

public class Sorter {
    public void selectionSort(int[] numbers) {
        for (int i = 0; i < numbers.length - 1; i++) {
            int leastPosition = i;
            for (int j = i + 1; j < numbers.length; j++) {
                if (numbers[j] < numbers[leastPosition])
                    leastPosition = j;
            }
            int temp = numbers[leastPosition];
            numbers[leastPosition] = numbers[i];
            numbers[i] = temp;
        }
    }
}

What is awry? I can’t find a missing assignment operator anywhere.

Answer 1

The problem, I think, is the last line of your code:

nums;

This is an expression, but not a statement; hence the complaint. If you want to examine the contents of nums, you can do something like:

System.out.println(Arrays.toString(nums));
