java was started but returned exit code=13 与查看java参数

<span style="font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);">遇到java was started but returned exit code=13这样的问题，首先想到eclipse与JDK 32 64不一致</span>
那么如何查看JDK是多少位滴来~~~一般是cmd java -version  好吧 发现没有显示多少位（默认32） 要是64的话 会显示的



额 如果之前有eclipse的话 阔以没事看一下 or  http://www.importnew.com/11370.html 查看这篇文章 不用ide跑java 程序

public class testSystemInfo {
public static void main(String[] args) {
Properties ht = System.getProperties();
Iterator<Entry<Object, Object>> itor = ht.entrySet().iterator();
while(itor.hasNext()){
Entry<Object, Object> entrys = itor.next();
System.out.println(entrys.getKey() + " : " + entrys.getValue());

}
// showKeys(ht);
// showValues(ht);
}

private static void showValues(Properties ht) {
// TODO Auto-generated method stub
Enumeration<Object> en = ht.elements();
while(en.hasMoreElements()){
System.out.println(en.nextElement());
}
}

private static void showKeys(Properties ht) {
// TODO Auto-generated method stub
Enumeration<?> en = ht.propertyNames();
while(en.hasMoreElements()){
System.out.println(en.nextElement());
}
}
}


sun.arch.data.model 这个参数就是你的JDK的多少位
