Help me put this into a method..

[mike bones]

Hello.

I'm a new java programmer trying to convert this prog into a method. What the prog does is converts a string to uppercase.

Code:

public class CaseChange
{
public static void main (String[] args)
{
String TestString = new String("Test String");

TestString = TestString.toUpperCase();
System.out.println("UPPER CASE " + TestString);

}
}


Can anyone help me convert this into a method? So that I can call it in the main?

Any help would be great.

I'm not exactly sure what you want as I think that there are several ways to do what I think you desire.

using static methods:

/**

 */
public class ChangeCaseStatic
 
    public static void myToUpper1(String myInputStr)
    {
        System.out.println("UPPER CASE: " + myInputStr.toUpperCase());
    }
    
    public static String myToUpper2(String myInputStr)
    {
        return myInputStr.toUpperCase();
    }
 
    public static void main(String[] args)
    {
        String myStr = "This is all very stupid, if you ask me.";
 
        myToUpper1(myStr);
 
        System.out.println("UPPER CASE: " + myToUpper2(myStr));
    }
}

or using classes:

/**

 */
public class ChangeCase
{
    // non static variables
    private String inputString = "";
    
    // instance methods
    
    public ChangeCase()
    {
        this.inputString = "";
    }
 
    public ChangeCase(String inputStr)
    {
        this.inputString = inputStr;
    }
    
    public String getInputString()
    {
        return inputString;
    }
    
    public void setInputString(String inputStr)
    {
        this.inputString = inputStr;
    }
    
    public String getAllUpper()
    {
        return inputString.toUpperCase();
    }
    
    public String getAllLower()
    {
        return inputString.toLowerCase();
    }
    
    public String getTitleCase()
    {
        String[] inputStrArr = inputString.split(" ");
        StringBuilder mySB = new StringBuilder();
        for (int i = 0; i < inputStrArr.length; i++)
        {
            String thisStr = inputStrArr[i];
            if (!thisStr.isEmpty() && !thisStr.equals(""))
            {
                mySB.append(Character.toUpperCase(thisStr.charAt(0)));
                if (thisStr.length() > 1)
                {
                    mySB.append(thisStr.substring(1).toLowerCase());
                }
                if (i != (inputStrArr.length - 1))
                {
                    mySB.append(" ");
                }
            }
        }
        return mySB.toString();
    }
    
    public static void main(String[] args)
    {
        ChangeCase cc = new ChangeCase("This is very stupid, if you ask me.");
        System.out.println(cc.getAllLower());
        System.out.println(cc.getAllUpper());
        System.out.println(cc.getTitleCase());
    }
 
}

ps: please learn about code tags so that your code is more readable.
