public static int looker(String x, String y) { int num1 = 0; int stringlength = x.length(); String str1 = y.toLowerCase(); String str2 = x.toLowerCase(); for (int i = 0; i < str1.length(); i++) { if (((i+stringlength)<str1.length())&&(str1.charAt(i)==str2.charAt(0))) { if (str1.substring(i, i+stringlength).equals(str2)) num1++; } } return num1; } a) What does (str1.substring(i, i+stringlength).equals(str2)) test? b) Why does the program create str1 and str2? c) Combine the two if statements in the easiest way possible. Write the simplest combined test, without the word if on the front, without any spaces except where required, and with parentheses around each unique Boolean term. Keep the test components that you use in the same order as they are now and do not rewrite any individual Boolean term that you use. d) If the user calls this method with ("meDo the crime better luck next time").what value will be returned by method looker? public static int looker(String x, String y) { int num1 = 0; int stringlength = x.length(); String str1 = y.toLowerCase(); String str2 = x.toLowerCase(); for (int i = 0; i < str1.length(); i++) { if (((i+stringlength)<str1.length())&&(str1.charAt(i)==str2.charAt(0))) { if (str1.substring(i, i+stringlength).equals(str2)) num1++; } } return num1; } a) What does (str1.substring(i, i+stringlength).equals(str2)) test? b) Why does the program create str1 and str2? c) Combine the two if statements in the easiest way possible.
