Greater than: a > b Greater than or equal to: a >= b Equal to a == b Not Equal to: a != bYou can use these conditions to perform different actions for different decisions.Java has the following conditional statements:Use if to specify a block of code to be executed, if a specifi...
System.out.println("num1 is greater than or equal to num2"); } else{ System.out.println("num1 is less than num2"); } if( num1 < num2 ){ System.out.println("num1 is less than num2"); } else{ System.out.println("num1 is not less than num2"); } if( num1 <= num2)...
Equality and Relational Operators == Equal to != Not equal to > Greater than >= Greater than or equal to < Less than <= Less than or equal to Conditional Operators && Conditional-AND || Conditional-OR ?: Ternary (shorthand forif-then-elsestatement) Type Comparison Operator instanceof Compa...
The equality and relational operators determine if one operand is greater than, less than, equal to, or not equal to another operand. The majority of these operators will probably look familiar to you as well. Keep in mind that you must use "==", not "=", when testing if two ...
The ternary operator evaluates whether the user’s “age” is equal to or greater than 16 (“age >= 16”). If the expression evaluates to true, the operator returns “This user is over 16.”. Otherwise, the operator returns This user is under 16. On the final line of our code, ...
The Collections API has been with us since JDK 1.2, but not all parts of it have received equal attention or love from the developer community. Algorithms, a more functional-centric way of interacting with collections, have been a part of the Collections API since its initial release, but ...

Returnstrueif the expression on the left evaluates to a value that is greater than or equal to the expression on the right. For more information, seeVariablesandConstants. A basic Boolean expression has this form: expression relational-operator expression ...
Before we wrap up, let’s put your knowledge of Java Ternary Operator (With Example) to the test! Can you solve the following challenge? Challenge: Write a function to check if a person can enter a club or not. If age is greater than or equal to 18, return "Can Enter". Otherwise...
