Java 字符串方法

Question

我有逗号分隔的字符串变量，例如:

String doctors = "doc_vijayan,doc_zubair,doc_Raja" 

但是我想从上面的字符串中删除“doc_”，首字母应该大写。我需要这样的输出:

String doctors1 = "Vijayan, Zubair, Raja"

怎么做？

你可以试试:

public String splitDoctors(String doctorsString){
    String[] doctors = doctorsString.split(",");
    boolean isFirst = true;
    StringBuilder sb = new StringBuilder();
    for(String doctor : doctors){
        if(!isFirst){
            sb.append(", ");
        }else{
            isFirst = false;
        }
        sb.append(doctor.substring(4,5).toUpperCase());
        sb.append(doctor.substring(5));
    }
    return sb.toString();
}
