regex - Java - Split string based on space and single quote but ignore two single quotes -

i want split string using space , single quote. 2 single quotes should ignored.

input:

name eq 'a''b' 

output should be:

name  eq  a''b 

i tried use

[^\\s\"(?<!')'(?!')]+|\"[^\"]*\"|(?<!')'(?!')[^(?<!')'(?!')]*(?<!')'(?!')" 

but not work.

the following 1 should suit needs:

'(?:[^']|'')+'|[^ ]+
