What type of operator determines whether either of two boolean conditions are true?
A relational operator compares two values and determines the relationship between them. For example,
Following is an example, Show Here's the output from this program:public class RelationalDemo { public static void main(String[] args) { //a few numbers int i = 37; int j = 42; int k = 42; System.out.println("Variable values..."); System.out.println(" i = " + i); System.out.println(" j = " + j); System.out.println(" k = " + k); //greater than System.out.println("Greater than..."); System.out.println(" i > j = " + (i > j)); //false System.out.println(" j > i = " + (j > i)); //true System.out.println(" k > j = " + (k > j)); //false; //they are equal //greater than or equal to System.out.println("Greater than or equal to..."); System.out.println(" i >= j = " + (i >= j)); //false System.out.println(" j >= i = " + (j >= i)); //true System.out.println(" k >= j = " + (k >= j)); //true //less than System.out.println("Less than..."); System.out.println(" i < j = " + (i < j)); //true System.out.println(" j < i = " + (j < i)); //false System.out.println(" k < j = " + (k < j)); //false //less than or equal to System.out.println("Less than or equal to..."); System.out.println(" i <= j = " + (i <= j)); //true System.out.println(" j <= i = " + (j <= i)); //false System.out.println(" k <= j = " + (k <= j)); //true //equal to System.out.println("Equal to..."); System.out.println(" i == j = " + (i == j)); //false System.out.println(" k == j = " + (k == j)); //true //not equal to System.out.println("Not equal to..."); System.out.println(" i != j = " + (i != j)); //true System.out.println(" k != j = " + (k != j)); //false } } Relational operators often are used with conditional operators to construct more complex decision-making expressions. The Java programming language supports six conditional operators—five binary and one unary—as shown in the following table. Conditional OperatorsVariable values... i = 37 j = 42 k = 42 Greater than... i > j = false j > i = true k > j = false Greater than or equal to... i >= j = false j >= i = true k >= j = true Less than... i < j = true j < i = false k < j = false Less than or equal to... i <= j = true j <= i = false k <= j = true Equal to... i == j = false k == j = true Not equal to... i != j = true k != j = false
One such operator is Note that in some instances, the second operand to a conditional operator may not be evaluated. Consider this code segment:0 <= index && index < NUM_ENTRIES The(numChars < LIMIT) && (...) && operator will return true only if both operands are true . So, if numChars is greater than or equal to LIMIT , the left-hand operand for && is false , and the return value of && can be determined without evaluating the right-hand operand. In such a case, the interpreter will not
evaluate the right-hand operand. This case has important implications if the right-hand operand has side effects, such as reading from a stream, updating a value, or making a calculation. When both operands are boolean, the operator What operator evaluates to true if both Boolean conditions are true?The & operator produces true only if both its operands evaluate to true . If either x or y evaluates to false , x & y produces false (even if another operand evaluates to null ).
Which operator determines whether two expressions are both true?This operator performs logical conjunction on two Boolean expressions. If both expressions evaluate to True, the AND operator returns True. If either or both expressions evaluate to False, the AND operator returns False.
What operator is used to combine two Boolean conditions?You can use the AND and OR operators to combine two or more conditions into a compound condition. AND, OR, and a third operator, NOT, are logical operators. Logical operators, or Boolean operators, are operators designed to work with truth values: true, false, and unknown.
What type of operators is used to determine the logic between two conditions?A logical operator is a symbol or word used to connect two or more expressions such that the value of the compound expression produced depends only on that of the original expressions and on the meaning of the operator.
