substring c# js java

String.SubString(int index,int length)

String.SubString(int start)

等效于

javascript

stringObject.substr(start,length)

stringObject.substr(start)

java

* @param      beginIndex   the beginning index, inclusive.
* @param      endIndex     the ending index, exclusive.

public String substring(int beginIndex, int endIndex)

与上面相对应的实现

public static String subString(String src, int startIndex, int length){

    return src.substring(startIndex, startIndex+length);

}
