Thefor-loopstatement in Java provides a compact way to iterate over the arrays or collection types using a counter variable that is incremented or decremented after each iteration. Programmers often refer to it as thetraditional “for loop”because of the way it repeatedly loops until a particular...
Java 8 Stream APIprovides ways to iterate over a collection and operate over each element.Streamcan be used as analternative to the for-loop. privatestaticList<Integer>list=newArrayList<>();list.stream().forEach(consumerAction); 1.2. Enhanced for-loop In this technique, advancedfor-each statem...

As Java developers, we often write code that iterates over a set of elements and performs an operation on each one. TheJava 8 streams libraryand itsforEachmethod allow us to write that code in a clean, declarative manner. While this is similar to loops,we are missing the equivalent of t...
For starters, think of memory leakage as a disease and Java’sOutOfMemoryError(OOM, for brevity) as a symptom. But as with any disease,not all OOMs necessarily imply memory leaks: an OOM can occur due to the generation of a large number of local variables or other such events. On the...

This is an interesting feature to work around cases where a hot loop is inside a method that has not itself become hot. The following formula (see source here and here) is used by the Compilation Policy to decide whether to create a compilation request at level 3, for a method that is...
other by sending and receiving byte streams over a connection. To send a message from your application to another application, you need to know the IP address as well as the port number of the socket of the other application. In Java, a socket is represented by the java.net.Socket class...
