Java编程——String replaceAll(String regex,Stirng replace)，将字符串中满足正则表达式的部分替换为给定内容

package day02;
/**
 * 将字符串中满足正则表达式的部分替换为给定内容
 * String replaceAll(String regex,Stirng replace)
 * @author Administrator
 *
 */

public class StringDemo4 {
	public static void main(String[] args){
		String str = "ab123sdab4543das756as876asd";
		str = str.replaceAll("\\d+", "#num#");  //"\d+",任意多个数字字符
		System.out.println(str);
	}
}

运行结果：

package day02;
/**
 * 
 * @author Administrator
 *
 */

public class StringDemo5 {
	public static void main(String[] args) {
		String regex = "(wqnmlgb|cnm|dsb|rnmb|sb|db|djb)";
		String message = "wqnmlgb!你怎么这么mei!com!你真shuai";
		message = message.replaceAll(regex, "***");
		System.out.println(message);
	}

}
