The {} chars are substitution placeholders - basically means to place the found file (with full path) in that place. So if you run:
find . -name "*.java" -exec cat {}
And there's exactly two Java files under the current dir named "Main.java" and "DB.java", then this is what ultimately get executed:
cat src/main/java/Main.java
cat src/main/java/DB.java
Of course, if there are more .java files they would be found/matched then exec'd
HTH!

What does {} specify after the exec command?
