String[] shortString=longString.split(":"); for(int i=0;i<shortString.length;i++){ System.out.println (shortString[i]); } 得到:aa、bb、cc。 可以证明没有问题,可是如果longString="aa|bb|cc",就有问题了,代码如下: String longString="aa|bb|cc"; String[] shortString=longString.split(...
String[] array = permissionString.split("\\+"); Java中String.split方法传入的参数是一个RegularExpr,是一个正则表达式。 在正则表达式中,+是转义字符,\也是转义字符 引号内要双写\\,第一个\转义第二个\,也就是\\表示一个\,转义后的\再转义+,所以\\+表示+。
我想说,在JavaScript里,分出的是["b","",":and:f","",""],比较贴近我们的思维,但是Java里面split的一段源码这样写道: // Construct result int resultSize = matchList.size(); if (limit == 0) while (resultSize > 0 && matchList.get(resultSize-1).equals("")) resultSize--; String[] r...

In Java, a string is a sequence of characters. For example, "hello" is a string containing a sequence of characters 'h', 'e', 'l', 'l', and 'o'. In this tutorial, we will learn about strings in Java with the help of examples.
text/java 複製 String str = "abc"; </blockquote> is equivalent to: <blockquote>text/java 複製 char data[] = {'a', 'b', 'c'}; String str = new String(data); </blockquote> Here are some more examples of how strings can be used: <blockquote>...
