求教一个正则表达式(replaceall()),该如何处理

求教一个正则表达式(replaceall())
String   s1= "User   ID:${id}name:${name} "
我想用replaceall()
将${id}变为001,${name}变为zhang

怎么写replaceall()的参数?

String s1= "User ID:${id}name:${name} ";
System.out.println(s1.replaceAll( "\\$\\{id\\} ", "001 ").replaceAll( "\\$\\{name\\} ", "zhang "));

s1.replaceAll( "\\$\\{id\\} ", "001 ").replaceAll( "\\$\\{name\\} ", "zhang ")
