JAVA过滤HTML代码和截取字符串的类(包括测试用例)

1、JAVA过滤HTML代码和截取字符串的类（包括测试用例）import java.util.regex.Pattern;public class FunctionUtil public static void main(String args) String str = "<p><font size="2"><span style="mce_style="font-size: 10.5pt">"+ "依据绩abc效管理体系的规定，公司决定于</span><span

2、 style=" mce_style="font-size: 10.5pt">"+ "2008</span><span style=" mce_style="font-size: 10.5pt">年</span><span style=" "+ "mce_style="font-size: 10.5pt">12</span><span style=" mce_style="f

8、ls(str) return ""int d = 0; / byte lengthint n = 0; / char lengthfor (; n < str.length(); n+) d = (int) str.charAt(n) > 256 ? d + 2 : d + 1; if (d > width) break;if (d > width) n = n - ellipsis.length() / 2;return str.substring(0, n > 0 ? n : 0) + ellipsis; return str = str.
