linux安装oracle静默建库时抛Exception in thread "main" java.lang.NullPointerException 求大神帮忙

java.lang.NullPointerException：这个提示是dbca抛出的java进程错误。

解决：

检查JDK安装路径和配置；

帮忙写个JAVA 读写ini配置文件小程序!!!!!

其实使用 JDK 里面提供的 Properties 最方便。 相关使用方法可以自己去查看 JDK 的API文档。 package product;import java.awt.event.ActionEvent;

经测试，可用，正常。就是文件路径你自己配好。

Java中如何设置读取ini配置文件？

// 读取一般的属性文件

FileInputStream fin=new FileInputStream("my.ini"); // 打开文件

Properties props=new Properties();                 // 建立属性类

props.load(fin);                                   // 读入文件

fin.close();                                       // 关闭文件

java 向ini配置文件中写入值。

Java读取和修改ini配置文件，参考如下：

/*

* ConfigurationFile.java

*

*/

import java.io.BufferedReader;

import java.io.BufferedWriter;

import java.io.FileReader;

import java.io.FileWriter;

import java.io.IOException;

import java.util.regex.Matcher;

import java.util.regex.Pattern;

/**

* 这是个配置文档操作类，用来读取和配置ini配置文档

* @author 由月

* @version 2004-08-18

* @修改 2008-05-22

*/

public final class ConfigurationFile {

/**

* 从ini配置文档中读取变量的值

* @param file 配置文档的路径

* @param section 要获取的变量所在段名称

* @param variable 要获取的变量名称

* @param defaultValue 变量名称不存在时的默认值

* @return 变量的值

* @throws IOException 抛出文档操作可能出现的io异常

*/

public static String getProfileString(

String file,

String section,

String variable,

String defaultValue)

throws IOException {

String strLine, value = "";

BufferedReader bufferedReader = new BufferedReader(new FileReader(file));

boolean isInSection = false;

try {

while ((strLine = bufferedReader.readLine()) != null) {

strLine = strLine.trim();

//strLine = strLine.split("[;]")[0];

Pattern p;

Matcher m;

p = Pattern.compile("\\["+section+"\\]");

m = p.matcher((strLine));

if (m.matches()) {

p = Pattern.compile("\\["+section+"\\]");

m = p.matcher(strLine);

if (m.matches()) {

isInSection = true;

} else {

isInSection = false;

}

}

if (isInSection == true) {

strLine = strLine.trim();

String[] strArray = strLine.split("=");

if (strArray.length == 1) {

value = strArray[0].trim();

if (value.equalsIgnoreCase(variable)) {

value = "";

return value;

}

} else if (strArray.length == 2) {

value = strArray[0].trim();

if (value.equalsIgnoreCase(variable)) {

value = strArray[1].trim();

return value;

}

} else if (strArray.length 2) {

value = strArray[0].trim();

if (value.equalsIgnoreCase(variable)) {

value = strLine.substring(strLine.indexOf("=") + 1).trim();

return value;

}

}

}

}

} finally {

bufferedReader.close();

}

return defaultValue;

}
