如何使用java替换字符串中的字符呢？
以下实例中我们使用 java String 类的 replace 方法来替换字符串中的字符：
StringReplaceEmp.java 文件

public static void main(String args[]){
String str="Hello World";
System.out.println( str.replace( 'H','W' ) );
System.out.println( str.replaceFirst("He", "Wa") );
System.out.println( str.replaceAll("He", "Ha") );
}
}
以上代码实例输出结果为：
