还可以用箭头函数简写这种方式,省略function age.forEach(function (value){ console.log(value);//21,23,12,77,34,67,11,45 }) //2.使用for循环语句进行循环 for(var i=0;i<age.length;i++){ console.log(age[i]);//结果相同 } //3.for...in(不推荐) //for(var index in object){} for...
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 ...
for(int num:numbers){if(num==target){return???;// do not know the index of num}}For-each only iterates forward over the arrayinsingle steps// cannot be converted to a for-each loopfor(int i=numbers.length-1;i>0;i--){System.out.println(numbers[i]);}For-each cannot process two...
Iteration over the collection must not be done in the mybatis XML. Just execute a simple Insertstatement in a Java Foreach loop. The most important thing is the session Executor type. SqlSessionsession=sessionFactory.openSession(ExecutorType.BATCH);for(Model model : list) { session.insert("ins...
for (Element e : elements) { doSomething(e); } Advantage of for-each loop Slight performance advantage over an ordinary for loop since it computes the limit of the array index only once. It's not error propone for Nested iteration over multiple collections. ...

The import statement lets you override definitions in the imported file with definitions in your own stylesheet. for-each loops (section 8) Loop over a collection of items and process each one in turn. choose (case statement) for conditional processing (section 9.2) Branch to one of multiple ...
Loop Through a HashMap Loop through the items of aHashMapwith afor-eachloop. Note:Use thekeySet()method if you only want the keys, and use thevalues()method if you only want the values: Example // Print keysfor(Stringi:capitalCities.keySet()){System.out.println(i);} ...
