The differences between egetMessage() and toString() methods in Java

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. #
