i have a string like the following [Lcom.hexgen.ro.request.CreateRequisitionRO;
how to get the string com.hexgen.ro.request.CreateRequisitionRO
this only from [Lcom.hexgen.ro.request.CreateRequisitionRO;
in java. there are few cases where i get com.hexgen.ro.request.CreateRequisitionRO;
so i also have to check whether the given string has the format of what i am expecting like com.hexgen.ro.request.CreateRequisitionRO
Please help me to correct it.
You should be using a regex:
String input = "com.hexgen.ro.request.CreateRequisitionRO"; //OR "[Lcom.hexgen.ro.request.CreateRequisitionRO;"
Pattern p = Pattern.compile("(\\[L)*([\\w\\.]+)(\\;)*");
Matcher m = p.matcher(input);
while(m.find()){
System.out.println(m.group(2));
}
如何仅从[Lcom.hexgen.ro.request.CreateRequisitionRO;中获取字符串com.hexgen.ro.request.CreateRequisitionRO;
String res = str.substring(2,str.length-1);
Here is a code:
String toBeFixed = "[Lcom.hexgen.ro.request.CreateRequisitionRO;";
String toReplaceWith =toBeFixed.replaceAll("\\[L", "").replaceAll("\\;","");
System.out.println(toReplaceWith);
This might work in your case, considering you have string replacement query:
public void test(){
String s1 = "[Lcom.hexgen.ro.request.CreateRequisitionRO";
String s2 = "com.hexgen.ro.request.CreateRequisitionRO";
System.out.println(getClassName(s1));
System.out.println(getClassName(s2));
}
public String getClassName(String s){
if(s.startsWith("\\[L")){
s = s.substring(2, s.length()-1);
}
return s;
}
Use substring function
String url="com.hexgen.ro.request.CreateRequisitionRO";
int n=url.length();
String url1=url.substring(
