Arrays.sort() in Java - GeeksforGeeks
It sorts arrays in ascending order by default (for primitives and Comparable objects). For objects, you can customize sorting using Comparator. It uses Dual-Pivot QuickSort for primitives and TimSort for objects (optimized for performance).

Quick and dirty method to sort array using method in java without using Array.sort() method?
Whatever problem you're having, it likely has nothing to do with the "pass by value nature of Java". Java is technically a "pass-by-value" language, but when you pass an object (including an array), the value you're passing is itself a reference to the object, not the object itself. The array is not copied, only the reference is copied. So changes to an array inside a method are reflected outside of the method. And so the code you posted does in fact work to sort a list of scores in descending order, even if it's placed inside a method: https://godbolt.org/z/PrhscbsPG If you're having some problems with your code, please be more specific about what you're doing, what you expect to happen and what you're seeing instead.

Okay. Why does it do that? You have the code in front of you. You can trace it through, line by line. What happens at each step? What does the bag look like before you add the item? Where should the item go? If you know how to use a debugger, do so. If you don't know how to use a debugger then start adding println statements to the code so that you know exactly what is going on. print out everything you can think of. Your code is doing things in an odd way, IMHO. I would normally expect that you'd skip over the items with a weight of less than the new item and then, when you find an item that is heavier than yours, "move up" everything after that to make space for yours. You start off by putting your item in the very first position, which seems very wrong to me. Your next question is probably going to be "How do I fix this code?". TBH, I don't think you "fix" this so much as rewrite it from scratch. Write down a clear set of instructions, stating what the function will do. Super detailed. Then implement that.

Loops are also very useful to learn about, esp When using arrays,
int[] array = new int[10];
Random rand = new Random();
for (int i = 0; i < array.length; i++)
array[i] = rand.nextInt(100) + 1;
Arrays.sort(array);
System.out.println(Arrays.toString(array));
// in reverse order
for (int i = array.length - 1; i >= 0; i--)
System.out.print(array[i] + " ");
System.out.println();

Java program for Sorting Elements In An Array
August 8, 2025 - This article covers multiple sorting methods in Java with complete code examples, theoretical explanations, and complexity analysis. What is Sorting? Sorting refers to the process of arranging data in a specific order, typically in ascending or descending order. Sorting makes data easier to search, analyze, and visualize. Sorting algorithms differ based on performance, memory usage, and the way they handle equal elements (stability). Example Problem Statement: Given an array of integers, sort the elements in ascending order using different sorting techniques in Java.

Array is built-in almost all programming languages, e.g., C++, Python ('array' is called as 'list' in Python), Java, etc. We can use (Compact) Array to implement List ADT. We can use (Compact) Array to solve many classic problems. When not being used as a List ADT implementation (where positional order matters), it is often beneficial to first · sort the elements first so that we can utilize faster algorithms.

Sorting Arrays and Lists in Java
November 22, 2024 - We can use any comparison-based sorting algorithm for this problem, but since we are sorting by length, we can use a modified version of quick sort that chooses the pivot based on the length of the strings rather than their values. This approach is called quick sort with median-of-three partitioning and has a time complexity of O(nlogn) in the average case. ... Suppose we have an array of integers that we want to sort in descending order which contains only 20 elements.

October 22, 2024 -
My previous research:
https://stackoverflow.com/questions/8938235/sort-an-array-in-java
I've code for it but I ma having tough time implementing it as a method because of pass by value nature of java.
// some sorting technique
for (int i = 0; i < scores.length; i++) {
for (int j = i; j < scores.length; j++) {
if (scores[j] > scores[i]) {
int temp = scores[i];
scores[i] = scores[j];
scores[j] = temp;
// swap names as well
String temp2 = names[i];
names[i] = names[j];
names[j] = temp2;
}
}
}
Implementing this as a method seems really troublesome because the changes done inside method aren't reflected outside of method
