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
Summary: It can be seen that the information obtained by e.toString() includes the exception type and exception detailed message, while e.getMessage() only obtains the detailed message string of the exception.
