创建java可执行文件

Question

What is the command-line equivalent (Linux) of

gcc -o executable file.c

for a jar file? (Java instead of gcc)

I know it is possible to do because at my school, all that is necessary is writing "mars" (the MIPS simulator) in command-line

Answer 1

To execute a Java JAR file, run the following command, replacing YourJarFile.jar with the filename of your JAR file.

java -jar YourJarFile.jar

EDIT: There is no way to execute a Java JAR like

./YourJarFile.jar

because the Java Runtime Environment must interpret the JAR file, not the operating system's sh .

Answer 2

There is no direct, native, command-line equivalent. @Deltik provides the closest compatible method.

Answer 3

javac myfile.java

假设你安装了JDK;）

Answer 4

To compile Foo.java and Bar.java:

javac Foo.java Bar.java

To put the compiled class files in a jar:

jar cvf classes.jar Foo.class Bar.class

Note that if you put your classes in packages, which you should, your class files will be in a sub-directory and you will have to change the jar command accordingly.
