Merge Sort in Java with Example

Merge sort In computer science, merge sort (also commonly spelled mergesort) is an O(n log n) comparison-based sorting algorithm. Most implementations produce a stable sort, which means that the implementation preserves the input order of equal elements in the sorted output. Mergesort is a divide and conquer algorithm. Divide and conquer algorithms divide the original data into smaller sets of dataContinue reading “Merge Sort in Java with Example”

Understanding ConcurrentHashMap Collections in Java

ConcurrentHashMap is a Map implementation like HashMap and Hashtable, with additional support for concurrency features: Unlike Hastable or synchronizedMap which locks the entire map exclusively to gain thread-safety feature, ConcurrentHashMap allows concurrent writer and reader threads. That means it allows some threads to modify the map and other threads to read values from the map at the same time, while Hashtable or synchronizedMap allows only one thread to work on theContinue reading “Understanding ConcurrentHashMap Collections in Java”

Treemap in java collections with examples

TreeMap is Red-Black tree based NavigableMap implementation. It is sorted according to the natural ordering of its keys. The TreeMap in Java is used to implement Map interface and NavigableMap along with the Abstract Class. The map is sorted according to the natural ordering of its keys, or by a Comparator provided at map creationContinue reading “Treemap in java collections with examples”

Java hashcode() with example

Java hashCode(): Java Object hashCode() is a native method and returns the integer hash code value of the object. The general contract of hashCode() method is: Multiple invocations of hashCode() should return the same integer value, unless the object property is modified that is being used in the equals() method. An object hash code valueContinue reading “Java hashcode() with example”
