Count number of people who has department starting with given department(from parameter list) ignoring case ?

Question

See more:

rollNumberStream has String eg PE11115,HI34565,Pe5567,Pe5137,pe4324,EE21258 and I need to count number of people in specified department(Passed in arguments as dept) case insensitive.

If pe is passed it should consider PE11115, Pe5137,pe4324 all of these

What I have tried:

public static int getCount(Stream<string> rollNumberStream, String dept) {

long count_roll=rollNumberStream.filter(x->x.startsWith(dept)).count();
int count=(int)count_roll;
return count;

}// this working fine with case sensitive but i want to ignore cases

Solution 1

Convert them both to lowercase before you compare them.
Convert the dept before you start comparing, and use toLower in your lambda to convert x before calling startsWith

Solution 2

String dept_lower=dept.toLowerCase();
long count_roll=rollNumberStream.filter(x->x.toLowerCase().startsWith(dept_lower)).count();
