What does source / binary format mean in java? what is it?
This property appears in the properties of the netbeans project / source category.
So, if you are working with a project that needs to be compatible with JDK 7, 6, 5 ... so that the IDE can recognize unsupported functions in your code.
The IDE will compile with the appropriate parameters -sourceand -target.
-source
-target
I do not use NetBeans, but I assume that it represents the settings of the Java compiler version - some versions activate language functions (for example, activates generators, for example) and reduce backward compatibility.
