upper/lower case question

[choubix alex]

hello,

I've understood how to display decimals and change strings to upper/lower case (so many online resources on Java!)

I was wondering what should be best in the following code where I convert a string to:
1st character: upper string, subsequent characters, lower case. (line 25, first block of code)

the code is quite lengthy...

instead of calling "myaccount.GetAnyVariableNameHere" in the out.println(), shall I create a variable and call it ?
if so: should the name be the same as in the setter/getter or different?

thanks!

 

import static java.lang.System.out;
import java.text.DecimalFormat;

public class UseAccount {

public static void main(String[] args) {
	// TODO Auto-generated method stub
	Account myAccount = new Account();
	
	//DecimalFormat money = new DecimalFormat("$0.00");
	DecimalFormat money = new DecimalFormat("'$' #,###.##");
	
	myAccount.setFirstName("John");
	myAccount.setLastName("doe");
	myAccount.setAddress("21a white house Avenue");
	myAccount.setBalance(200000000.5250);
	

	//Lower Case
	out.println(myAccount.getFirstName().toLowerCase());
	
	//Upper case for the 1st character of the String 
	out.println(myAccount.getLastName().substring(0,1).toUpperCase() +myAccount.getLastName().substring(1));
	
	//Upper case the whole string
	out.println(myAccount.getAddress().toUpperCase());
	
	
	// shows getBalance with $ sign first and 2 decimals
	// uses static import java.text.DecimalFormat
	// requires declaration: DecimalFormat new_variable = new DecimalFormat("$0.00");
	// output needs:  new_variable.format(getter);
	
	out.println(money.format(myAccount.getBalance()));
	
	//show getBalance on screen, no decimals
	//out.printf("%.0f", myAccount.getBalance());    
	}
} 

and

 

public class Account {

	/**
	 * @param args
	 */
		
		private String firstName;
		private String lastName;
		private String address;
		private double balance;

		public void setFirstName(String name1) {
			firstName = name1;
		}
		public String getFirstName(){
			return firstName;
		}
		
		public void setLastName(String name2) {
			lastName = name2;
		}
		public String getLastName(){
			return lastName;
		}
		
		public void setAddress(String address1) {
			address = address1;
		}
		public String getAddress(){
			return address;
		}

		public void setBalance(double balance1){
			balance = balance1;
		}
		
		public double getBalance(){
			return balance;
		}
		

}

Almost all of your code is irrelevant for your question. I would just create a capitalize function:

 public class SubStringTest
{
	public static String capitalize(String s)
	{
		if(s!=null && s.length() > 0)
		{
			return s.substring(0,1).toUpperCase() + s.substring(1);
		}else
			return "";
	}

	public static void main(String... args)
	{
		System.out.println(capitalize(null));
		System.out.println(capitalize(""));
		System.out.println(capitalize("wouter"));
	}
}

Or, if you don't mind the dependency, you could use the StringUtils class of the Apache Commons library.
