Question

Using java on Eclipse

Make a class 'StringMethods'.
It contains a private instance String variable.
Add these instance methods to your StringMethods class:
Constructor that takes a String literal and assigns it to the private String variable. Include getters and setters.
Check if this string equals the exact string contents of another string returns boolean true/false.
reallyEquals(String string)
Check if this string matches another but ignores letter casing.
caselessEquals(String string)
Check if the string shares an interned reference with another string.
internedEquals(String string)
A method that prints out the string. printThis()
A method that returns a char of the largest value in the string. getTopChar()
A method that prints out the string arranged in alphabetical order. printAlpha()
*Must handle the mixture of Capital and Lowercase letters*
For Example "OnceUponATime" Should output "AceeimnnOopTU"
A method that returns an int array of the ASCII char values of the characters in the string. getAsciiArray()
Make a method that returns a substring. getSubstring(int startlndex, int endlndex)
Make a static Class level overloaded method that returns a substring. getSubstring(String inputString, int startlndex, int
endlndex)

Expert Solution

Step 1

public class StringMethods {

    private String line;

    public StringMethods(String line) {
        this.line = line;
    }

    public boolean reallyEquals(String string) {
        return line.equals(string);
    }

    public boolean caselessEquals(String string) {
        return line.equalsIgnoreCase(string);
    }

    public boolean iternedEquals(String string) {
        string = string.toLowerCase();
        String thisString = line.toLowerCase();

        return string.contains(thisString) || thisString.contains(string);
    }

    public void printThis() {
        System.out.println(line);
    }

    public char getTopChar() {
        if (line.length() == 0) return ' ';
        char top = line.charAt(0);
        for (char ch : line.toCharArray()) {
            if (top < ch) top = ch;
        }
        return top;

    }
