val string: String = "HelloWorld" //字符串对象

fun main(args: Array<String>) {
println(string == fromChars) //相当于equals方法，比较其内容
println(string === fromChars) //比较是不是同一个对象
val arg1: Int = 2
val arg2: Int = 8
println("$arg1 + $arg2 = ${arg1 + arg2}") //字符串模板
//Hello "Jack"
val sayHello: String = "Hello \"Jack\""
println(sayHello) //输出转义字符
//$salary
println("\$salary") //输出转义字符
//原生字符串
val rawString: String = """
You never like the world
I just not so happy
"""
println(rawString)
println(rawString.length) //打印原生字符串的长度
