Scala Array ==()用法及代码示例

Array#==() 是一个 Array 类方法，用于执行两个数组之间的比较。它检查两个数组是否相等。

用法：Array.==()

参数：用于比较的数组

Return: true ：如果数组相等
false：如果数组不相等

示例#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

示例#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
