Java Programming Using the class below, please ), write a static method called parse that parses a String for balanced parentheses. we seek only to determine that the symbol ‘{‘ is balanced with ‘}’. parse accepts a single String parameter and returns an int. If parse returns a minus 1, then there are no errors, otherwise, parse should return the position within the String where an error occurred. For example parse(“{3 + {4/2} }”) would return -1 parse(“{ { 4*X}”)...

You shall implement six static methods in a class named BasicBioinformatics. Each of the methods will perform some analysis of data considered to be DNA. DNA shall be represented arrays of chars containing only the characters A, C, G and T. In addition to the six methods you will implement, six other methods exist in the class, which use Strings instead of char arrays to represent DNA. These other methods simply invoke the methods you are to implement, so all...

Using maps in Java. Make a public class called ExampleOne that provides a single class (static) method named firstOne. firstOne accepts a String array and returns a map from Strings to Integer. The map must count the number of passed Strings based on the FIRST letter. For example, with the String array {“banana”, “apples”, “blueberry”, “orange”}, the map should return {“b”:2, “a”:1, “o”:1}. Disregard empty Strings and zero counts. Retrieve first character of String as a char using charAt, or,...

Java program Write a class called Animal that contains a static variable called count to keep track of the number of animals created. Your class needs a getter and setter to manage this resource. Create another variable called myCount that is assigned to each animal for each animal to keep track of its own given number. Write a getter and setter to manage the static variable count so that it can be accessed as a class resource
