line3 The 'singleton' identifier was very distracting, whats it doing? and the use of SafeDeposit just about everywhere further confused me. Could someone explain what is happening here please

[code = java]
class SafeDeposit {

private static SafeDeposit singleton;

public static SafeDeposit getInstance(int code) {

if(singleton == null)
singleton = new SafeDeposit(code);
return singleton;
}

private int code;
private SafeDeposit(int c){code = c;}
int getCode() {return code;}
}

public class BeSafe {
//insert lots of code here
}[/code]
