Ruby 符号 == 函数

Symbol#==() : ==()是一个Symbol类的方法，用于比较两个Symbol对象。

语法。符号.==()

参数。符号值

返回：如果两个符号相等则为真，否则返回假。

例子 #1 :

# Ruby code for Symbol.==() method
  
# declaring Symbol 
a = :aBcDeF
  
# declaring Symbol
b = :"\u{e4 f6 fc}"
  
# declaring Symbol
c = :ABCDEF
  
# Symbol 
puts "Symbol a : #{a}\n\n"
puts "Symbol b : #{b}\n\n"
puts "Symbol c : #{c}\n\n\n\n"
  
  
# == form 
puts "Symbol a == form : #{a == c}\n\n"
puts "Symbol b == form : #{b == b}\n\n"
puts "Symbol c == form : #{c == a}\n\n"

输出:

Symbol a : aBcDeF

Symbol b : äöü

Symbol c : ABCDEF



Symbol a == form : false

Symbol b == form : true

Symbol c == form : false

例子 #2 :

# Ruby code for Symbol.==() method
  
# declaring Symbol 
a = :geeks
  
# declaring Symbol
b = :"\u{e5 f6 f3}"
  
# declaring Symbol
c = :GEEKS
  
# Symbol 
puts "Symbol a : #{a}\n\n"
puts "Symbol b : #{b}\n\n"
puts "Symbol c : #{c}\n\n\n\n"
  
  
# == form 
puts "Symbol a == form : #{a == c}\n\n"
puts "Symbol b == form : #{b == b}\n\n"
puts "Symbol c == form : #{c == a}\n\n"

输出:

Symbol a : geeks

Symbol b : åöó

Symbol c : GEEKS



Symbol a == form : false

Symbol b == form : true

Symbol c == form : false
