If the two String objects have the same address references then it returns true, otherwise false. The idea is to convert all the strings and substring to lowercase before check with 3.2 So, we can also check the substring like this :Mkyong.com is providing Java and Spring tutorials and code snippets since 2008. Source code in Mkyong.com is licensed under the Java supports the usual logical conditions from mathematics:You can use these conditions to perform different actions for different decisions.In the example below, we test two values to find out if 20 is greater than This method returns true if a specified sequence of characters is present in a given string, otherwise it returns false. Strings are used for storing text. 18.

Java counts positions from zero.

Since the value of the number is 10, the test expression evaluates to true.Hence code inside the body of if is executed.. Now, change the value of the number to a negative integer.

If the condition is In the example above, time (20) is greater than 18, so the condition is In the example above, time (22) is greater than 10, so the However, if the time was 14, our program would print "Good day. Java have a String pool under which Java manages the memory allocation for the String objects.
