Ruby Hash eql?用法及代码示例


Hash#eql?()是一个Hash类方法,它检查两个Hash数组是否相等。

用法:Hash.eql?()

参数:散列值


返回:true-如果两个哈希数组相等,则返回false

范例1:

# Ruby code for Hash.eql?() 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} 
   
   
# equal? Value 
puts "Hash a equal? form:#{a.eql?(b)}\n\n"
   
puts "Hash b equal? form:#{b.eql?(c)}\n\n"
   
puts "Hash c equal? form:#{c.eql?(a)}\n\n"

输出:

Hash a equal? form:false

Hash b equal? form:false

Hash c equal? form:false

范例2:

# Ruby code for Hash.equal?() 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} 
   
   
# equal? Value 
puts "Hash a equal? form:#{a.eql?(b)}\n\n"
   
puts "Hash b equal? form:#{b.eql?(c)}\n\n"
   
puts "Hash c equal? form:#{c.eql?(a)}\n\n"

输出:

Hash a equal? form:false

Hash b equal? form:false

Hash c equal? form:false
