ubuntu下面的java一键运行脚本

java的运行分为编译+执行两部分.

怪麻烦的,所以写个脚本一键运行.如下:

--------------------------------------------------------------------------------------------------

java_compile.sh

#!/bin/bash
file_name="$1"

name=${file_name%.*}
echo file name is: $name

javac $1 
java $name

chmod u+x java_compile.sh

--------------------------------------------------------------------------------------------------

.bashrc的配置

######################JAVA_HOME########################
export JAVA_HOME=~/Java/jdk1.8.0_131
export SPARK_HOME=~/bigdata/spark-2.3.1-bin-hadoop2.7
export CLASSPATH=.:${JAVA_HOME}/lib:${JAVA_HOME}/lib/*.jar:$SPARK_HOME/jars/*
export PATH=$PATH:${JAVA_HOME}/bin:${JAVA_HOME}/jre/bin
alias java=/home/appleyuchi/java_compile.sh

--------------------------------------------------------------------------------------------------

使用方法,任意文件夹下面建立文件helloworld.java

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

保存并关闭.

当前路径下打开终端,输入java helloworld.java

运行结果如下:
file name is: helloworld
Hello World!
