p "区切り文字:特手文字"
p ["study","skill",].join("tokyo")
p "区切文字列:-"
p ["study","skill","smart"].join("-")
p "区切文字列:+"
p ["study","skill","smart"].join("+")
#!/usr/bin/ruby
p "区切り文字：スペース"
p ["study","skill","become","smart"].join(" ")
p "区切文字：,"
p ["study","skill","become","smart"].join(",")
p "区切り文字:特手文字"
p ["study","skill",].join("tokyo")
p "区切文字列:-"
p ["study","skill","smart"].join("-")
p "区切文字列:+"
p ["study","skill","smart"].join("+")
#!/usr/bin/ruby
p "区切り文字：スペース"
p ["study","skill","become","smart"].join(" ")
p "区切文字：,"

p "区切り文字:特手文字"
p ["study","skill",].join("tokyo")
p "区切文字列:-"
p ["study","skill","smart"].join("-")
p "区切文字列:+"
p ["study","skill","smart"].join("+")
結果
"区切り文字：スペース"
"study skill become smart"
"区切文字：,"
"study,skill,become,smart"
"区切り文字:特手文字"
"studytokyoskill"
"区切文字列:-"
"study-skill-smart"
"区切文字列:+"
"study+skill+smart"
"区切り文字：スペース"
"study skill become smart"
"区切文字：,"
"study,skill,become,smart"
"区切り文字:特手文字"
"studytokyoskill"
"区切文字列:-"
"study-skill-smart"
"区切文字列:+"
"study+skill+smart"
"区切り文字：スペース" "study skill become smart" "区切文字：," "study,skill,become,smart" "区切り文字:特手文字" "studytokyoskill" "区切文字列:-" "study-skill-smart" "区切文字列:+" "study+skill+smart"
