idea常用for循环快捷键

iterations 快捷键

Live Templates

其实下面介绍的所有for循环都在live templates里面，当然可以自定义：

迭代器for循环

iter

Iterate iterable | Array in J2SDK 5 syntax

1. 1. for (String arg : args) {
   2.  
   3. }

itar

Iterate elements of array

1. 1. for (int j = 0; j < args.length; j++) {
   2. String arg = args[j];
   3.  
   4. }

itco

Iterate elements of java.util.Collection

1. 1. for (Iterator iterator = collection.iterator(); iterator.hasNext(); ) {
   2. Object next = iterator.next();
   3.  
   4. }

iten

Iterate java.util.Enumeration

1. 1. while (enumeration.hasMoreElements()) {
   2. Object nextElement = enumeration.nextElement();
   3.  
   4. }

itit

Iterate java.util.Iterator

1. 1. while (iterator.hasNext()) {
   2. Object next = iterator.next();
   3.  
   4. }

itli

Iterate elements of java.util.List

1. 1. for (int j = 0; j < list.size(); j++) {
   2. Object o = list.get(j);
   3.  
   4. }

ittok

Iterate tokens from String

1. 1. for (StringTokenizer stringTokenizer = new StringTokenizer(); stringTokenizer.hasMoreTokens(); ) {
   2. String s = stringTokenizer.nextToken();
   3.  
   4. }

itve

Iterate elements of java.util.Vector

1. 1. for (int j = 0; j < vector.size(); j++) {
   2. Object elementAt = vector.elementAt(j);
   3.  
   4. }

以上快捷键在IDEA中输入it后，在IDEA的代码提示中均可以找到。

普通for循环

fori

create iteration loop 

1. 1. for (int j = 0; j < ; j++) {
   2.  
   3. }

foreach

create a for each loop

1. 1. for (:
   2. ) {
   3.  
   4. }
