终端下简单地运行 Java 代码

脚本如下

#!/bin/bash
set -e

fileName=$1
if [ -z "$fileName" ]; then
    echo "Parameters error!"
    exit	
fi

if [ ! -d classes ]; then
    mkdir classes
fi
className=${fileName%%.*}
javac $className.java -d ./classes/
java -classpath ./classes $className

public class FinalTest
{
    public static void main(String[] args)
    {
        System.out.println("Hello world!");
    }
}

配合Tab键、↑应该可以高效地操作

bogon:Java fang$ ls
FinalTest.java	test.sh
bogon:Java fang$ ./test.sh FinalTest.java 
Hello world!
