In this blog we will know how to sort map by it's value.
Here are the steps to sort map by value in ascending or descending order
Step-1. Let we have a map .
Now if we need to sort it by it's value in ascending order
def map = [apple:3, banana:2, mongo:1]
// ascending order
map = map.sort {it.value}
println map
// output [mongo:1, banana:2, apple:3]
Now if we need to sort it by it's value in ascending order
// descending order
map = map.sort {a, b -> b.value <=> a.value}
println map
// output [apple:3, banana:2, mongo:1]
