    The boolean expression is the expression which can be evaluated to true or false. This true/false is called boolean value. An if statement is used to check a condition which often contains the boolean expression which can either evaluate to true or false.

    a. x > y > z

    This line means that the value of variable x is greater than the value of variable y and the value of variable y is greater than the value of variable z.

    This means:

    x is greater than y AND y is greater than z

    x > y AND y > z

    in JAVA x > y && y > z

    using if statement if (x > y && y > z)

    it can also be written as: if (x > y && x > z && y >z)

    b. x and y are both less than 0

    This statement means that the value of variable x and the value of variable y are less than 0

    This means: (x AND y) = 0

    in JAVA (x&&y) = =0

    using if statement: if ((num&&hum) = =0)

    This can also be written as x < 0 AND y < 0

    In JAVA x < 0 && y < 0

    using if statement if (x < 0 && y < 0)

    c. neither x nor y is less than 0

    This statement means that neither the value of x variable nor the value of y variable is less than 0. This clearly means that the value of x and value of y both values are greater than or equal to 0.

    this means:

    x > = 0 AND y > = 0

    In JAVA x > = 0 && y > = 0

    Using if statement if (x > = 0 && y > = 0)

    It can also be written as (x && y > = 0)

    if (x && y > = 0)

    d. x is equal to y but not equal to z

    This statement means that the value of x is equal to the value of y but the value of x is not equal to the value of z.

    This means

    x = y but x ≠ z

    x=y AND x≠z

    In JAVA x==y && x!=z

    Using if statement if (x = = y && x! = z)

    it can also be written as if (x = = y && y! = z)

    If x is equal to y so this means that the value of x and y will be the same and both the values will not be equal to the value of z.
