Ruby 数组==()方法

Array#==() 是一个数组类方法，它在两个数组之间进行比较。它检查这两个数组是否相等。

语法。Array.==()

参数。用于比较的数组

返回：true : 如果数组相等

false : 如果数组不相等

例子 #1 :

# Ruby code for ==() method
# checking equality
   
# differencing arrays
a = [18, 22, 33, 4, 5, 6]
   
# differencing arrays
b = [18, 22, 33, 4, 5, 6]
   
# differencing arrays
c = [18, 22, 33, 40, 50, 6]
   
# checking array equality
puts "comparison : #{a == b}\n\n"
   
# checking array equality
puts "comparison : #{a == c}\n\n"
   
# checking array equality
puts "comparison : #{b == c}\n\n"

输出:

comparison : true

comparison : false

comparison : false

例子 #2 :

# Ruby code for ==() method
# checking equality
   
# differencing arrays
a = ["abc", "xyz", "dog"]
   
# differencing arrays
b = ["cat", "cat", "dog"]
   
# differencing arrays
c = ["cat", "cat", "dog"]
   
# checking array equality
puts "comparison : #{a == b}\n\n"
   
# checking array equality
puts "comparison : #{a == c}\n\n"
   
# checking array equality
puts "comparison : #{b == c}\n\n"

输出:

comparison : false

comparison : false

comparison : true
