In this tutorial, we shall see how to check if two Strings are equal in Java using the method String.equals(String anotherString). Also, we shall go through an example Java program to ignore the case of the characters in the string, and check if two Strings are equal. Examples 1. Che...
, indicating a non-empty string. Checking if str1 is null or empty: The code uses an if-else statement to check if str1 is null or empty. It first checks if str1 is equal to null using the == operator. If the condition evaluates to true, it means str1 is null or empty, and...

Lists in Java are ordered by nature. So,two lists are considered to be equal if they contain the exact same elements in the same order.In this tutorial, we’ll see how to compare two Lists for equality in Java. We’ll also cover ways in which we can just compare the elements in two...
I am new to Java and JDeveloper and I am trying to debug and add custom code to one of the java files in JDeveloper to check a string value (TotalAmt) to be greater or equal to zero - if it is then I need to post a warning message as the value cannot...

This quick tutorial demonstrated ways of testing if two Java Lists are equal. Two List implementations are considered equal when they have the same elements in the same order. We studied how to assert that the two Lists are the same or are equal using JUnit, TestNG, AssertJ, and plain Jav...
