尝试在MacBook Pro上执行Java文件时出现“找不到文件”

Question

Am trying to execute a java method, am having my java first.java which I compiled using javac first.java , After which a class file got created in the same path but when I tried executing the class file using command javac first.class it throws error saying file not found . Any idea by the way I have both JDK and JRE in the path variable. Am using java 1.8

Answer 1

java first使用java first执行， javac用于编译。
