List and Set both are interfaces. They both extends Collection interface. In this post we are discussing thedifferences between List and Set interfacesin java. List Vs Set 1) List is an ordered collection it maintains the insertion order, which means upon displaying the list content it will di...
In this guide, you will learndifference between ArrayList and LinkedList in Java.ArrayListandLinkedListboth implements List interface and their methods and results are almost identical.

In Java, the & operator is a bitwise AND operator, and the && operator is a logical AND operator.The difference between these operators is in the way they evaluate their operands.The & operator evaluates both operands, regardless of their value. It then performs a bitwise AND operation on ...
The constructor takes two parameters: exception message, and a cause, which may be any subclass of Throwable. Let’s write a fake implementation for findAll() function: public List<String> findAll() throws SQLException { throw new SQLException(); } Now, in SimpleService let’s call ...

If we run the above code – which produces the difference betweentext1andtext2– printing the variablediffwill produce this output: [Diff(EQUAL,"ABC"), Diff(DELETE,"DE"), Diff(INSERT,"FG"), Diff(EQUAL,"LMN")] In fact, the output will be alist ofDiffobjects, each one beingformed by...
Basically, they are just two different implementations of List interface.LinkedList is implemented with a double-linked list; ArrayList is implemented
Difference between String Class and String buffer class String class is Immutable whereas String Buffer class is Mutable. String class consumes more memory whenever we append too many strings, whereas String buffer consumes very less memory.
