It is the equality operator used to check if a variable is equal to another variable or literal.Į.g. ![]() It is the assignment operator used for assigning a value to a variable. If m=5 and n=2 then what will be the output of m and n after execution that will store in (a) & (b)? an expression is a combination of operators and operands. Next printing takes place from next line.ĭifferentiate between an operator and an expression.Īn operator is a symbol or sign used to specify an operation to be performed whereas an expression is a set of variables, constants and operators i.e. Next printing takes place from the same line. It prints data to the console and places the cursor in the next line. It prints data to the console but the cursor remains at the end of the data in the same line. It works on the principle of USE-THEN-CHANGE.Īfter the execution of these two statements, both a and b will have the value of 100.Īfter the execution of these two statements, a will have the value of 100 and b will have the value of 99. It works on the principle of CHANGE-THEN-USE. (d) Prefix operator and Postfix operator Prefix Operator Here, value of c will be 10 as at least one of the operands is true. Here, value of c will be 5 as one of the operands is false. The result of an operation involving relation operators is a boolean value - true or false. Relational operators compare their operands to check if the operands are equal to ( = ), not equal to ( != ), less than ( ), greater than equal to ( >= ) each other. Relational operators are used to determine the relationship between the operands. Here, the addition arithmetic operator, represented by the symbol + will add 10 and 20. As an example consider the below statement: ![]() They are called Binary Arithmetic operators. Other arithmetic operators operate upon two operands. They are called Unary Arithmetic operators. A few arithmetic operators operate upon one operand. Operands of arithmetic operators must be of numeric type. Question 3Īrithmetic operators are used to perform mathematical operations on its operands. The different types of operators are Arithmetical, Logical and Relational. ![]() Z = x * x * x + y * y * y - x * y / 3 Answer the following questions Question 1Īn operator is a symbol or sign used to specify an operation to be performed in Java programming. Y = 2 * (l * b + b * h + l * h) Question 7 S = u * t + (1.0 / 2) * a * t * t Question 4 ⇒ q = -15 Write the Java expressions for the following: Question 1 ![]()
