Print characters and their frequencies in order of occurrence using a LinkedHashMap in Java

// Java implementation of the approach
import java.util.LinkedHashMap;

public class GFG {

    // Function to print the characters and their
    // frequencies in the order of their occurrence
    static void printCharWithFreq(String str, int n)

        // which the input is supplied
        LinkedHashMap<Character, Integer> lhm
            = new LinkedHashMap<Character, Integer>();

        // For every character of the input string
        for (int i = 0; i < n; i++) {

            // Using java 8 getorDefault method
            char c = str.charAt(i);
            lhm.put(c, lhm.getOrDefault(c, 0) + 1);
        }

        // Iterate using java 8 forEach method
        lhm.forEach(
            (k, v) -> System.out.print(k + " " + v));
