&& (AND) and || (OR) in IF statements

In Java, the && and || operators are used in if statements to combine multiple conditions.

The && operator (also known as the logical AND operator) is a binary operator that returns true if both operands are true, and false if either operand is false. Here is an example of how to use the && operator in an if statement:

if (x > 0 && y > 0) {
  // both x and y are positive
}

The || operator (also known as the logical OR operator) is a binary operator that returns true if either operand is true, and false if both operands are false. Here is an example of how to use the || operator in an if statement:

if (x > 0 || y > 0) {
  // either x or y is positive (or both are positive)
}

It is important to note that the && and || operators have different precedence than the comparison operators (>, <, ==, etc.). This means that they are evaluated before the comparison operators. To ensure that the conditions are evaluated in the correct order, you can use parentheses to specify the order of evaluation.

For example, the following if statement checks if x is greater than y and z is less than y:

if ((x > y) && (z < y)) {
  // x is greater than y, and z is less than y
}
