- Given the String String str = “Zhrx.aghkio.Gko123”; (a) Write Java code using the String class methods indexOf and substring to extract the three string surrounded by the periods. In other words String s1 will contain Zhrx, String s2 will contain aghkio and String s3 will contain Gko123. (b) Write a method of the form public static String minstr(String str1, String str2) which returns the string which is “smaller” based on the decimal values of the characters in the string. Thus, Zaa would be “smaller” than bxy because the character Z has a lower decimal values than b. Use the String method compareTo as part of your code. (c) In main, print the value returned by minStr(minStr(s1,s2),s3)Java Question - Which option is correct? Question - Given the following code, which is the correct statement to call an overloaded method named "subIt"? class Sample { static int subIt(int x, int y) { return x-y; } static double subIt(double x, double y) { return x-y; } static char subIt(char x, char y) { return (char) ((int) x - (int) y); } static void subIt(int x) { System.out.println(x-5); } static void subIt(int x, int y, int z) { System.out.println(x-y-z); } } Group of answer choices a - System.out.print(subIt(3.15, 8.72)); b - subIt(8, 4); c - subIt('A', 'B'); d - subIt(35); e- System.out.print(subIt(35, 12, 7));Please code in java and dont use extremely advanced methods, please dont make change in the code .. edit from where it is mentionedWrite a program to draw a right-justified triangle given the height as input.
