Invoking "Run" button of Eclipse via code

Question

I have created a sample eclipse plugin development with a button.

@PostConstruct
public void createPartControl(Composite parent) {
    
    Button button = new Button(parent, SWT.PUSH);
    button.setText("button");        
    button.addSelectionListener((SelectionListener) new SelectionAdapter() {
        @Override
        public void widgetSelected(SelectionEvent e) {
            System.out.println(e);
        }
    });
}

I want to initiate eclipse run for a other java file(any other java class) when this button is clicked. Is there any way to programmatically control the run button of the eclipse?
