In Java, we can sort collections of data using various sorting algorithms and Java’s built-in sorting capabilities provided by the java.util.Collections class or the Arrays class. Learn by examples. Related Tags Java Sorting Guides Java Comparator Tutorials How to Sort an Array, List, Map ...
External-Memory Sorting in Java: useful to sort very large files using multiple cores and an external-memory algorithm. The versions 0.1 of the library are compatible with Java 6 and above. Versions 0.2 and above require at least Java 8. This code is used in Apache Jackrabbit Oak as well ...
Because most built-in types in C# implement the interface, it is possible to cast to and let the built-in type handle the comparison. If the as ; cast succeeds for both and then you can return If you are not comparing built-in types, but instead comparing another complex type such as...

.append(o1.getTimeStamp(), o2.getTimeStamp()) .toComparison(); } (All three versions are equivalent, but the plain Java version is the most verbose and hence most error-prone one. All three solutions assume that botho1.getActivation()ando1.getTimestamp()implementComparable)....
In tests I ran (on Intel architecture), I actually found that: when the compareTo() involves a single comparison, using a subtraction instead of comparisons makes no appreciable difference; when two comparisons are involved, using subtraction as above (so that our method has just a single ...
