說在前面

手巧太慢，快捷鍵。

iterations 快捷鍵

Live Templates

其實下面介紹的所有for迴圈都在live templates裡面，當然可以自定義：

迭代器for迴圈

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);
    
}

以上快捷鍵在IDEA中輸入it後，在IDEA的程式碼提示中均可以找到。

普通for迴圈

fori

create iteration loop 

for (int j = 0; j < ; j++) {
    
}

foreach

create a for each loop

for (:
     ) {

}
