I have a String,
String a = Roll No 5 To 40;
I want to get that 5 and 40 values into Different variables, Like String b = 5 , c= 40
This values can Change to anything,like 50 TO 100 OR 10 TO 90 and so on Any Ideas How can I achieve that?
String a = Roll No 5 To 40; To get 5, I converted a into String array, Iterated on it if matches("[0-9] then append in StringBuilder Will break if T comes In case of 40, With same String "[\d]+[\d] tried matching with this pattern
Thanks in Advance Akshay
It is convenient to use Stream API to convert the string into int[]:
String a = "Roll No 5 To 40";
int[] ints = Arrays.stream(a.split("\\D+")) // split the string by non-digits
.filter(s -> !s.isEmpty()) // ignore empty strings
.mapToInt(Integer::parseInt)// get int value
.toArray();
System.out.println(Arrays.toString(ints));
Output
[5, 40]
If the string format is always "Roll No VAL1 To VAL2" you can do simple string manipulation:
String a = "Roll No 5 To 40";
int index_of_To = a.indexOf("To");
int index_of_No = a.indexOf("No");
String val1 = a.substring(index_of_No + 3,index_of_To).strip();
String val2 = a.substring(index_of_To + 3).strip();
Kindly note that this is a very ad hoc technique of doing this and is not very flexible.
Integer.valueOfor similar:for (String s : text.split("\\D+")) { System.out.println(Integer.valueOf(s)); }
