Precedence is showing the order in which operators are evaluated while the code runs.
| ||
Level | Operator(s) | Name(s) |
1 | new () | object creation, explicit parentheses |
| () {} [] | method call, closure, literal list/map | |
| . .& .@ | member access, method closure, field/attribute access | |
| ?. * *. *: | safe dereferencing, spread, spread-dot, spread-map | |
| ~ ! (type) | bitwise negate/pattern, not, typecast | |
| [] ++ — | list/map/array index, post inc/decrement | |
2 | ** | power |
| 3 | ++ — + – | pre inc/decrement, unary plus, unary minus |
| 4 | * / % | multiply, div, remainder |
| 5 | + – | addition, subtraction |
| 6 | << >> >>> .. ..< | left/right (unsigned) shift, inclusive/exclusive range |
7 | < <= > >= in instanceof as | less/greater than/or equal, in, instanceof, type coercion |
| 8 | == != <=> | equals, not equals, compare to |
9 | =~ ==~ | regex find, regex match |
| & | binary/bitwise and | |
| 10 | ^ | binary/bitwise xor |
| 11 | | | binary/bitwise or |
| 12 | && | logical and |
| 13 | || | logical or |
| 14 | ? : | ternary conditional |
15 | ?: | elvis operator |

I have left the table intact showing all possible operators that are allowed in groovy programming language.
I have highlighted the ones we discussed in the previous posts.
However keep in mind that doing scripts in application composer you will not be using most of this operators.
