如何对在Java中保存为字符串的变量X和否定变量X'字母进行排序?
Example: String string = "B*A'*D*H'"; result must
String sortedString="A'*B*D*H'";

变量是否总是用 分隔*
?在那种情况下,它会很简单:
String in = "B*A'*D*H'";
String[] vars = in.split("\\*");
Arrays.sort(vars);
// Java is missing a simple php-like join function ;-(
StringBuilder sorted = new StringBuilder();
for(String s: vars){
sorted.append(s);
sorted.append("*");
}
sorted.deleteCharAt(sorted.length()-1);
你完成了;-)
