In this example i m not able to count "manoj" in the given string...how i can do this..
String text = "manoj kumjjjartiwarimanojmanoj";
char[] line = text.toCharArray();
char[] temp = "manoj".toCharArray();
int count=0;
for (int i =0; i < line.length; i++) {
int t =0;
for (int j = 0; j < temp.length; j++) {
if(line[i]==temp[j]){
t=1;
}
else{
t=0;
}
}
if(t==1){
count=count+1;
}
}
System.out.println(count);
You can use a combination of substring and startsWith of the String class directly:
String text = "manoj kumjjjartiwarimanojmanoj";
String search = "manoj";
int count = 0;
for (int i=0; i < text.length() - search.length(); i++) {
if (text.substring(i).startsWith(search)) {
count++;
}
}
System.out.println(count);
Prints 2
This will also count all occurrences in cases like searching for "aa" in "aaaaaa" (resulting in 5).
It can be done with various method , you should really search this on google before asking, but i am providing a code
String text = "manoj kumjjjartiwarimanojmanoj";
Pattern p = Pattern.compile("manoj");
Matcher m = p.matcher(text);
int count = 0;
while (m.find())
{
count +=1;
}
String pattern="manoj"
String text = "manoj kumjjjartiwarimanojmanoj";
String text2 = text.replaceAll (pattern, "")
(text.length() - text2.length())/pattern.length ()
Result: 3, is it correct?
Note, that a resulting manoj, like in input "mamanojnoj" will not be replaced by replaceAll, which might be in your interest.
