一天一段scala代码(十二)
为了更好的驾驭spark,最近在学习scala语言特性,主要看《快学scala》,顺便把一些自己认为有用的代码记下来。
package examples
object Example12 extends App{
def mulBy1(factor:Double)=(x:Double)=>factor*x
def mulBy2(factor:Double)(x:Double)=factor*x
val triple = mulBy1(3)
println(triple(8))
println(mulBy1(3)(8))
println(mulBy2(3)(8))
def myUntil1(myCondition: =>Boolean)(myBlock: =>Unit)
{
if(!myCondition)
{
myBlock
myUntil1(myCondition)(myBlock)
}
}
var x=10
myUntil1(x==0)
{
x-=1
println(x)
}
def myUntil2(myCondition: =>Boolean)(myBlock: ()=>Unit)
{
if(!myCondition)
{
myBlock()
myUntil2(myCondition)(myBlock)
}
}
x=10
myUntil2(x==0){()=>
x-=1
println(x)
}
val add : Int => Int =>Int = x => y => x + y
println(add(1)(2))
val add2:(Int) =>( Int =>Int )= (x) => (y => x + y)
println(add2(1)(2))
}
