说在前面

手巧太慢，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

 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 (:
     ) {

}
