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
    
    for (String arg : args) {
    }

itar
    Iterate elements of array
    
    for (int j = 0; j < args.length; j++) {
    String arg = args[j]; 
    }

itco
    Iterate elements of java.util.Collection
    
    for (Iterator iterator = collection.iterator(); iterator.hasNext(); ) {
    Object next = iterator.next();
    }
    
    
    iten
    Iterate java.util.Enumeration
    
    while (enumeration.hasMoreElements()) {
    Object nextElement = enumeration.nextElement(); 
    }
    
    
    itit
    Iterate java.util.Iterator
    
    while (iterator.hasNext()) {
    Object next = iterator.next(); 
    }
    
    
    itli
    Iterate elements of java.util.List
    
    for (int j = 0; j < list.size(); j++) {
    Object o = list.get(j); 
    }
    
    
    ittok
    Iterate tokens from String
    
    for (StringTokenizer stringTokenizer = new StringTokenizer(); stringTokenizer.hasMoreTokens(); ) {
    String s = stringTokenizer.nextToken();
    }
    
    
    itve
    Iterate elements of java.util.Vector
    
    for (int j = 0; j < vector.size(); j++) {
    Object elementAt = vector.elementAt(j); 
    }
    
    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 
    
    for (int j = 0; j < ; j++) {
    }
    
    
    foreach
    create a for each loop
    
    for (:
    ) { 
    }
