here is the code...

String string = "superboymother"; // string variable contains the string that u want to search

int aCount = 0;
int eCount = 0;
int iCount = 0;
int oCount = 0;
int uCount = 0;

char[] stringBrocken = string.toCharArray();
for(int i=0; i<stringBrocken.length; i++) {
if(brockenString[i] == 'a') {
aCount += 1;
}
if(brockenString[i] == 'e') {
eCount += 1;
}
if(brockenString[i] == 'i') {
iCount += 1;
}
if(brockenString[i] == 'o') {
oCount += 1;
}
if(brockenString[i] == 'u') {
uCount += 1;
}
}


// Now you got the counts for each letters

ranyodh you are too smart.... I was using String.indexOf() ....But your way looks better than mine if it is the matter of only a few letters or numbers.

String string = "superboymother"; // string variable contains the string that u want to search

int aCount = 0;
int eCount = 0;
int iCount = 0;
int oCount = 0;
int uCount = 0;

char[] stringBrocken = string.toCharArray();//i don't readily understand can example?
for(int i=0; i<stringBrocken.length; i++) {//i don't readily understand can example?
if(brockenString[i] == 'a') {//i don't readily understand can example?

aCount += 1;
}
if(brockenString[i] == 'e') {
eCount += 1;
}
if(brockenString[i] == 'i') {
iCount += 1;
}
if(brockenString[i] == 'o') {
oCount += 1;
}
if(brockenString[i] == 'u') {
uCount += 1;
}
}
