变量问题：
类变量和方法变量的区别是什么？
类变量：可以直接使用
方法变量：需要实例化后，才能使用该变量
案例一：
class Person
@@name = "Tom"
@@names = "Toms"
@@age = 10
def jek
@jj = "jj"
@@bb="wonter"
end
def Person.getName
return @@name
end
def Person.getNames
return @@names
end
def Person.getage
return @@age
end
end
class Xx < Person
def aa
puts "#{@@age}"
ll = Person.new
ll.jek
@bb = @@bb
puts "#{@bb}" end
end
puts Person.getNames
x = Xx.new
x.aa
父子类继承问题：
重写父类方法，或直接使用父类方法。
案例二：
class Father
def says
puts "I am father."
end
def fatherInfo
puts "father info."
end
end
class Son < Father
def sonInfo
puts "son info."
end
end
class Two < Father
def twoInfo
puts "two info."
end
end
#father = Father.new
son = Son.new
two = Two.new
#father.says
#father.fatherInfo
son.says
son.sonInfo
son.fatherInfo
two.twoInfo
two.says
传参问题：
类之间参数的传递与使用。
案例三：
class Father
def initialize name
@name = name
end
def says
puts "I am father."
end
def fat xx
@xname = xx
puts "I am father. #{@xname}"
end
end
class Son < Father
def sayss
puts "I am son. name: #{@name}"
end
def sonsays
puts "no : #{@name}"
end
end
son = Son.new "Tom"
#son.says
#son.sonsays
son.fat "wonter"
循环和判断问题：
涉及数组
案例四：
list1 = ["192.168.48.202","icare","log"]
list2 = ["192.168.48.101","tomcat","sysif"]
length = list1.length
length.times do |t|
#print "#{list2[t]} \n" if list2[t] = list1[t]
puts "ok list1:#{list1[t]} \n list2:#{list2[t]}"
else
puts "no"
end
end
puts "#################################################################"
for i in list1 do
print "#{i} "
end
puts "\n"
关于引入与通配：
load 'D:\Workspaces\Ruby2\control\CdkPkg.rb'
#load 'D:\Workspaces\Ruby2\control\Cdel_linkP.rb'
class Home
def test_linkpkg
pkg=ClinkPkg.new
pkg.linkPkg
end
# def test_del_linkP
# del=Cdel_linkP.new
# del.del_linkP
# end
end
t = Home.new
test_methods = t.public_methods.grep(/^test_/) # 把所有test_开头的方法找出来。
test_methods.each do |test|
t.send(test) # 执行每个测试用例。
end
其实不管什么语言，什么语法都是大同小异，关键就看怎么用的好，怎么用的顺手。
