IntelliJ IDEA or Android. Of course, you could use any language for a big project but unless you have specific requirenments (usually C-like performance), Java / C# is the best choice.
Photoshop - Needs C-like performance for image processing parts. If they started development today, I think they would go with a C# / C++ hybrid.
Facebook - The fact that they had to write their own PHP compiler is telling. PHP is nowdays quite similar to Java without the tooling, performance and massive ecosystem.
