You are in the Debug Perspective (see What is a Perspective?). You can switch back to the Java or JEE perspective (where most development activities are typically performed) by using the perspective switcher toolbar in the upper-right corner of the Eclipse window.
I suggest you learn about the use of Perspectives in Eclipse.
