Path file=new File(“d:/code/img.png”).toPath();寫(xiě)完后顯示沒(méi)有Path這個(gè)包
為什么我的Path file=new File(“d:/code/img.png”).toPath();這句話(huà)報(bào)錯(cuò)呢？一寫(xiě)完P(guān)ath下面就出現(xiàn)紅色下劃線(xiàn)，顯示壓根就沒(méi)有這個(gè)包，但我前面那些步驟都和老師視頻里寫(xiě)的一樣，都沒(méi)報(bào)錯(cuò)，就這一句會(huì)報(bào)錯(cuò)，這是為啥啊？

直接用File就好了，不需要Path

jdk使用1.8依然如此

Path file = new File("D:/Qrcode-zxing.png").toPath();我也是 File和topath（）下面一直有紅線(xiàn)
