一：简单应用
/**
*
* ‘
* &
* ‘
* &
* &
* ‘
* ‘
* ‘
* sources=sdcg‘hde&xyz‘dfa&&ad‘‘‘
* result=sdcghdexyzdfaad
*/
public static void main(String[] args) {
String regex="‘|&";
Pattern pattern=Pattern.compile(regex);
String sources="sdcg‘hde&xyz‘dfa&&ad‘‘‘";
Matcher matcher=pattern.matcher(sources);
while(matcher.find()){
System.out.println(matcher.group());
}
String result=matcher.replaceAll("");
System.out.println("sources="+sources);
System.out.println("result="+result);
}
二：特例：“\”在java的正则表达式需要写成“\\\\”
/** * * & * * & * & * sources=sdcg\hde&xyz\dfa&&ad‘‘‘ * result=sdcghdexyzdfaad‘‘‘ * * @param args */ public static void main(String[] args) { String regex="\\\\|&"; Pattern pattern=Pattern.compile(regex); String sources="sdcg\\hde&xyz\\dfa&&ad‘‘‘"; Matcher matcher=pattern.matcher(sources); while(matcher.find()){ System.out.println(matcher.group()); } String result=matcher.replaceAll(""); System.out.println("sources="+sources); System.out.println("result="+result); }
