By iterating over the characters of the string and counting how much each character occurs.

String text="ghkhwehrgjklwheorhnfgpwjelrgjwelrg";
text=text.toLowerCase();
int charNum=26; // the number of unique characters
int[] freq=new int[charNum];
for(int i=0;i<text.length();i++) {
freq[text.charAt(i)-'a']++;
}
for(int i=0;i<charNum;i++) {
System.out.println("Frequency of " + (char) (97 + i) +": " + freq[i]);
}
