If the condition is false, another block of code can be executed. While the two String objects above contain the same string values, they refer to different object references, so the System.out.println statement will not be executed.

The if-then Statement. Even if you have two separate String objects with the same content, comparing them with == will return false because they are two separate objects. Every programming language or application without logic can’t be complete. The == operator checks if two expressions refer to the exact same object. We will see how to write such type of conditions in the java program using control statements. The if/else statement executes a block of code if a specified condition is true.
