The relational greater than or equal to operator (>=) compares two values of the same numeric type and returns a Boolean true value if the left operand is numerically greater than or equal to the right operand. Otherwise, it returns false. That operator has the following syntax: operand1 '...

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...
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 ...
System.out.println("num1 is greater than num2"); } else{ System.out.println("num1 is not greater than num2"); } if( num1 >= num2 ){ System.out.println("num1 is greater than or equal to num2"); } else{ System.out.println("num1 is less than num2"); ...
Java equality or relational operator Sample Java condition Meaning of Java condition Equality operators = == x == y x is equal to y != x != y x is not equal to y Relational operators > > x > y x is greater than y < < x < y x is less than y ...
This operator checks whether first operand is greater than or equal to the second operand. Example of greater than or equal to operator: int a = 7; int b = 5; if (a >= b){ System.out.println("a is either equal or greater than b"); ...
