// Java program to Compare two strings
// lexicographically
public class GFG {
  
    // This method compares two strings
    // lexicographically without using
    // library functions
    public static int stringCompare(String str1, String str2)
    {
  
        int l1 = str1.length();
        int l2 = str2.length();
        int lmin = Math.min(l1, l2);
  
        for (int i = 0; i < lmin; i++) {
            int str1_ch = (int)str1.charAt(i);
            int str2_ch = (int)str2.charAt(i);
  
            if (str1_ch != str2_ch) {
                return str1_ch - str2_ch;
            }
        }
  
        // Edge case for strings like
        // String 1="Geeks" and String 2="Geeksforgeeks"
        if (l1 != l2) {
            return l1 - l2;
        }
  
        // If none of the above conditions is true,
        // it implies both the strings are equal
        else {
            return 0;
        }
    }
  
    // Driver function to test the above program
    public static void main(String args[])
    {
        String string1 = new String("Geeksforgeeks");
        String string2 = new String("Practice");
        String string3 = new String("Geeks");
        String string4 = new String("Geeks");
  
        // Comparing for String 1 < String 2
        System.out.println("Comparing " + string1 + " and " + string2
                           + " : " + stringCompare(string1, string2));
  
        // Comparing for String 3 = String 4
        System.out.println("Comparing " + string3 + " and " + string4
                           + " : " + stringCompare(string3, string4));
  
        // Comparing for String 1 > String 4
        System.out.println("Comparing " + string1 + " and " + string4
                           + " : " + stringCompare(string1, string4));
    }
}
