红宝石 |数组类 to_s()函数

to_s()是一个 Array 类方法,它返回数组元素的字符串表示形式。

示例 #1:

# Ruby code for to_s() method
  
# declaring array
a = [18, 22, 33, nil, 5, 6]
  
# declaring array
b = [1, 4, 1, 1, 88, 9]
  
# declaring array
c = [18, 22, nil, nil, 50, 6]
  
# to_s
puts "to_s : #{a.to_s()}\n\n"
  
# to_s
puts "to_s : #{b.to_s()}\n\n"
  
# to_s
puts "to_s : #{c.to_s()}\n\n"

输出 :

to_s : [18, 22, 33, nil, 5, 6]

to_s : [1, 4, 1, 1, 88, 9]

to_s : [18, 22, nil, nil, 50, 6]

示例 #2:

# Ruby code for to_s() method
  
# declaring array
a = ["abc", "nil", "dog"]
  
# declaring array
b = ["cow", nil, "dog"]
  
# declaring array
c = ["cat", nil, nil]
  
# to_s
puts "to_s : #{a.to_s()}\n\n"
  
# to_s
puts "to_s : #{b.to_s()}\n\n"
  
# to_s
puts "to_s : #{c.to_s()}\n\n"

输出 :

to_s : ["abc", "nil", "dog"]

to_s : ["cow", nil, "dog"]

to_s : ["cat", nil, nil]
