Exception e中e的getMessage()和toString()方法的区别:
示例代码1:
public class
TestInfo {
private
static String str =null;
public
static void main(String[] args) {
System.out.println("test
exception");
try
{
if(str.equals("name")){
System.out.println("test
exception");
}
}
catch (Exception e) {
System.out.println(e.toString());
System.out.println(e.getMessage());
}
}
}
输出结果:
; font-family:"
microsoft="" background-color:="" />
null
示例代码2:
public class TestInfo {
private static int m =
0;
public static void
main(String[] args) {
System.out.println("test
exception");
try {
m = 899/0;
} catch (Exception e)
{
System.out.println(e.toString());
System.out.println(e.getMessage());
}
}
}
输出结果:
java.lang.ArithmeticException: /
by zero
/ by zero
总结:由此可以看出,e.toString()获取的信息包括异常类型和异常详细消息,而e.getMessage()只是获取了异常的详细消息字符串。
