红宝石 |哈希替换()方法

Hash#replace() : replace()是一种 Hash 类方法,它用另一个散列的内容替换一个散列的内容。

示例 #1:

# Ruby code for Hash.replace() method
  
# declaring Hash value
a = {a:100, b:200}
  
# declaring Hash value
b = {a:100, c:300, b:200}
  
# declaring Hash value
c = {a:100}
  
  
# replace Value
puts "Hash a replace form : #{a.replace(b)}\n\n"
  
puts "Hash b replace form : #{b.replace(c)}\n\n"
  
puts "Hash c replace form : #{c.replace(a)}\n\n"

输出 :

Hash a replace form : {:a=>100, :c=>300, :b=>200}

Hash b replace form : {:a=>100}

Hash c replace form : {:a=>100, :c=>300, :b=>200}

示例 #2:

# Ruby code for Hash.replace() method
  
# declaring Hash value
a = { "a" => 100, "b" => 200 }
  
# declaring Hash value
b = {"a" => 100}
  
# declaring Hash value
c = {"a" => 100, "c" => 300, "b" => 200}
  
  
# replace Value
puts "Hash a replace form : #{a.replace(b)}\n\n"
  
puts "Hash b replace form : #{b.replace(c)}\n\n"
  
puts "Hash c replace form : #{c.replace(a)}\n\n"

输出 :

Hash a replace form : {"a"=>100}

Hash b replace form : {"a"=>100, "c"=>300, "b"=>200}

Hash c replace form : {"a"=>100}
