Compile and build with single command line Java (Linux)

An alias is not made to accept parameters, define a function like this:

jcar() { javac $1.java && java $1 ; }

Then use it:

jcar Program

(jcar was intended as an acronym for java-compile-and-run)

Adding on to enrico.bacis' answer, i personally don't like to have Program.class files cluttering up my workspace if i'm just testing a program, so i'd do

jcar() { javac $1.java && java $1 && rm $1.class}

in addition, i found it helpful to trap ctrl-c so that even if i end the program halfway, it still removes the .class

jcar() {
trap "rm $1.class" SIGINT SIGTERM
javac $1.java
java $1
rm $1.class
}

Since Java 11 you can use a single command
