get certain character from string java
String words = "Hi There"; //creating a string var named 'words'
char index = words.charAt(0); /* setting a variable 'index' to letter
'0' of variable 'words'. In this case, index = 'H'.*/
System.out.println(index); //print var 'index' which will print "H"how to grab each character from a string
// An easier way to extract each character would be:
string s = "abcde";
for (int i=0; i<s.size(); i++) {
cout << s[i];
}
// To test if a particular character is an integer, you would do this:
//test if s[i] is an int from 0-9
if (s[i] <= '9' && s[i] >= '0') {
return true;
