nao consigo executar programa executar programa

crie um programa no netbeans para exibir a frase "welcome to java programing" no terminal
compilei o programa direitinho, so que na hora de executar recebo a seguinte mesnsagem de erro:

Exception in thread "main" java.lang.NoClassDefFoundError: Welcome1 (wrong name: welcome1/Welcome1)
at java.lang.ClassLoader.defineClass1(Native Method)

Could not find the main class: Welcome1. Program will exit.

o que ta acontecendo????

Welcome.java

public class Welcome{

  public static void main(String[] args){

         System.out.println(""welcome to java programing");

  }

}

 

No terminal
compilar
javac Welcome.java
executar
java Welcome
welcome to java programing

O que aconteçeu foi que, vc criou a classe com o nome welcome1 e executou usando Welcome1

Neste caso o nome da classe deve ter o mesmo nome do arquivo.java.
Ex:

public class Welcome1 {
public static void main (String args[]){
System.out.println("Testando primeiro programa"):
}
}

javac Welcome1.java
[spolti@ulacti76512 ~]$ java Welcome1
Testando primeiro programa


Abs

esta e a tentativa no terminal:
