java two conditions in if statement

Показать описание
certainly! in java, you can use logical operators to combine multiple conditions in an `if` statement. this allows you to execute code based on more complex criteria. the two primary logical operators are:

1. **logical and (`&&`)**: the combined condition is true if both conditions are true.
2. **logical or (`||`)**: the combined condition is true if at least one of the conditions is true.

### using two conditions in an if statement

#### logical and (`&&`)

when using the logical and operator, the `if` statement will execute the block of code only if both conditions evaluate to true.

**example**:

**explanation**:
- in this example, we check if a person is at least 18 years old and has a driving license.
- the message "you are eligible to drive." will be printed only if both conditions are true.

#### logical or (`||`)

when using the logical or operator, the `if` statement will execute the block of code if at least one of the conditions is true.

**example**:

**explanation**:
- in this example, we check if it is either a weekday or a holiday.
- the message "you have a day off!" will be printed if at least one of the conditions is true.

### combining and and or

you can also combine both logical operators in a single `if` statement, using parentheses to clarify the order of evaluation.

**example**:

**explanation**:
- in this case, we check if the person is either under 25 and has a driving license or is a student.
- the discount message will be printed if either of the two combined conditions is true.

### conclusion

using multiple conditions in `if` statements in java allows you to create more complex and nuanced decision-making logic in your programs. remember to use parentheses to clarify the order of operations when mixing and and or conditions. this will help avoid logical errors and make your code easier to understand.
