2):临时配置方式:set path=%path%;C:\Program Files\Java\jdk\bin 特点:系统默认先去当前路径下找要执行的程序,如果没有,再去path中设置的路径下找。 classpath的配置: 1):永久配置方式:classpath=.;c:\;e:\ 2):临时配置方式:set classpath=.;c:\;e:\ ...
String类包含用于连接两个字符串的方法: string1.concat (string2相等); 这将返回一个新的字符串,它是string1,末尾添加了string2。 字符串通常与+运算符连接,如in“Hello”+“world”+“! 需要注意的是:当使用字符串的时候,如果超过行大小,则需要+连接比如如下: String quote = "Now is the time for all...
