Java 8 Journey Of For Loop In Java For To ForEach Examples
It provides programmers a new concise way of iterating over a collection The forEach method performs the given action for each element of the Iterable until all elements have been processed or the action throws an exception void forEach Consumer super T action This is the syntax of the forEach method Consumer interface Java forEach forEach on Java lists maps sets ZetCode. The program needs access to the iterator in order to remove the current element The for each loop hides the iterator so you cannot call remove Therefore the for each loop is not usable for filtering Similarly it is not usable for loops where you need to replace elements in a list or array as you traverse it In this example we shall take Java List and write two forEach statements for the list In the first forEach we shall execute a single statement like printing the value In the second forEach statement we shall execute an if else loop for each of the element in the list Example java
