For each loop has been introduced in Javastarting from JDK5. It aims to iterate sequentially through all the elements of a Collection or array. It is also there in other languages like C#, where it uses the keyword for-each. However, Java uses the keyword ‘for’ only to implement a fo...

Since Java 1.5, the for-each loop or enhanced for loop is a concise way to iterate over the elements of an array and a Collection.
InJava 8, with the introduction ofFunctional InterfaceΛ’s, Java architects have provided us with an Internal Iterator (forEach loop) supported byCollection frameworkand can be used with the collections object. This method performs a given action for each element of the collection. Let’s see ...
in for loop is evaluated on each iteration, if the condition is true then the statements inside for loop body gets executed. Once the condition returns false, the statements in for loop does not execute and the control gets transferred to the next statement in the program after for loop. ...
Classic for loop 首先,来看看classic for loop. List<String> birds =new ArrayList<String>() { { add("magpie"); add("crow"); add("emu"); } }; for (int i =0; i < birds.size(); i++) { String bird = birds.get(i); }
2. Java For-loop Example In the following program, we are iterating over an array ofintvalues. The array contains 5 elements so the loop will iterate 5 times, once for each value in the array. int[]array=newint[]{0,1,2,3,4};for(inti=0;i<array.length;i++){System.out.format(...
initialization-expression –The initialization expression is executed once before the loop begins. It initializes the loop. termination-expression –This is executed each time to check whether looping should terminate or continue. The looping continues to execute the code until it evaluates to true and...
