StackTraceElement equals(Object) in Java

equals(Object): This method is available in the java.lang.StackTraceElement class of Java.

Syntax:

boolean java.lang.StackTraceElement.equals(Object obj)

This method takes one argument. This method returns true if the specified object is another StackTraceElement instance representing the same execution point as this instance.

Two stack trace elements a and b are equal if and only if:

equals(a.getClassLoaderName(),b.getClassLoaderName()) && equals(a.getModuleName(), b.getModuleName()) && equals(a.getModuleVersion(), b.getModuleVersion()) && equals(a.getClassName(), b.getClassName()) && equals(a.getMethodName(), b.getMethodName()) equals(a.getFileName(), b.getFileName()) && a.getLineNumber() == b.getLineNumber() where equals has the semantics of Objects.equals.

Parameters: One parameter is required for this method.

obj: the object to be compared with this stack trace element.

Returns: true if the specified object is another StackTraceElement instance representing the same execution point as this instance.

Exceptions: NA

Approach

Java

package com.StackTraceElement;

public class StackTraceElementequals {
    public static void main(String[] args) {

        String declaringClass = "java.lang.String";
        String methodName = "length()";
        String fileName = "String.class";
        int lineNumber = 675;
        StackTraceElement stackTraceElement = 
          new StackTraceElement(declaringClass, methodName, 
                                        fileName, lineNumber);

        StackTraceElement stackTraceElement1 =
               new StackTraceElement(declaringClass, methodName, 
                                        fileName, lineNumber);

        System.out.println(stackTraceElement.equals(stackTraceElement1));
    }
}

Output:

true
