---

---

Description

The Java StackTraceElement getMethodName() method returns the name of the method containing the execution point represented by this stack trace element.

Declaration

Following is the declaration for java.lang.StackTraceElement.getMethodName() method

public String getMethodName()

Parameters

NA

Return Value

This method returns the name of the method containing the execution point represented by this stack trace element.

Exception

NA

Example: Getting Current Thread Method Name using StackTraceElement

The following example shows the usage of Java StackTraceElement getFileName() method. In this program, we've defined a function named function2() which gets the method name from StackTraceElement of current thread. Another function named function1() is used to instantiate the StackTraceElementDemo class and call the function2() method. In main method, we've called the function1() method and result is printed.

package com.tutorialspoint;

public class StackTraceElementDemo {

   public static void main(String[] args) {
      function1();
   }
 
   public static void function1() {
      new StackTraceElementDemo().function2();
   }
 
   public void function2() {
      int i;
      System.out.println("method name : ");

      // print stack trace
      for( i = 1; i <= 3; i++ ) {
         System.out.println(Thread.currentThread().getStackTrace()[i].
         getMethodName());
      }
   }
}   

Output

Let us compile and run the above program, this will produce the following result −

method name :
function2
function1
main

Example: Getting Method Name using ArithmeticException's StackTraceElement

The following example shows the usage of Java StackTraceElement getMethodName() method. In main method, we've created three int variables where one variable is carrying zero value. In try-catch block, we've created a divide by zero scenario to raise an ArithmeticException. In catch block, we've handled the ArithmeticException, retrieved an array of StackTraceElement from it using getStackTrace() method and then using getMethodName() method on first element of the array, the method name is printed.

package com.tutorialspoint;

public class StackTraceElementDemo {

   public static void main(String[] args) {

      // variables to store int values
      int a = 0, b = 1, c;

      try {
         // being divide by zero, this line will throw an ArithmeticException
         c = b / a;
      }catch(ArithmeticException e) {
         // get the array of StackTraceElement
         StackTraceElement[] stackTraceElements =  e.getStackTrace();
         // print the line number
         System.out.println(stackTraceElements[0].getLineNumber());
      }
   }
}  

Output

Let us compile and run the above program, this will produce the following result −

main

Example: Getting Line Number using Exception's StackTraceElement

The following example shows the usage of Java StackTraceElement getMethodName() method. In main method, we've created three int variables where one variable is carrying zero value. In try-catch block, we've created a divide by zero scenario to raise an ArithmeticException. In catch block, we've handled the Exception, retrieved an array of StackTraceElement from it using getStackTrace() method and then using getMethodName() method on first element of the array, the method name is printed.

public class StackTraceElementDemo {

      // variables to store int values
      int a = 0, b = 1, c;

      try {
         // being divide by zero, this line will throw an ArithmeticException
         c = b / a;
      }catch(Exception e) {
         // get the array of StackTraceElement
         StackTraceElement[] stackTraceElements =  e.getStackTrace();
         // print the method name
         System.out.println(stackTraceElements[0].getMethodName());
      }
   }
