[Quote=引用 1 楼 justinavril 的回复:]
Java codeString string="1*11/33?2323";

System.out.println(string.replaceAll("\\*","").replaceAll("/","").replaceAll("\\?",""));

不是 说 一个 吗？

[justinavril]

		 String string = "1*11/33?2323"; 
		 
		 System.out.println(string.replaceAll("\\*?/?\\??", ""));

String str = "1*11/33?2323" ;
String regex = "(\\*|/|\\?)" ;
str = str.replaceAll(regex, "") ;
System.out.println(str) ;

[「已注销」]

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class Regular {

    public static void main(String[] args) {
        String string = "1*11/33?2323";

        Matcher matcher = Pattern.compile("\\*|/|\\?").matcher(string);

        StringBuffer sbuf = new StringBuffer();

        while (matcher.find()) {
            matcher.appendReplacement(sbuf, "");
        }
        matcher.appendTail(sbuf);

        System.out.println(sbuf.toString());
    }

}

str.replaceAll("\\*|\\/|\\?","");

[longds7]

public class Test {
	public static void main(String[] args){
		String str = "1*11/33?2323"; 
		System.out.println(str.replaceAll("[^0-9]", ""));
	}
}
