why do we use cherry pick in git code example

Example 1: git cherry pick commit

# from the  branch you want to apply changes

# it will bring all commit changes but also stage them
git cherry-pick <commit-hash> 

# it will bring all commit changes but leave them unstaged

git cherry-pick -n <commit-hash> #OR
git cherry-pick --no-commit <commit-hash>

Example 2: git cherry pick commit

#Checkout the branch you want to apply the commit to.
git checkout master

#Cherry pick using the commit hash.
git cherry-pick <commit-hash>

#If cherry picking from a public branch use "-x" to add a standardized commit message.
git cherry-pick -x <commit-hash>
