The correct answer is: to break out of some block of code to do something only if a condition is true.
We use if statements in Java to conditionally execute a block of code, only if a certain condition is met. The basic syntax of an if statement is:
if (condition) {
// block of code to be executed if condition is true
}
The block of code inside the { } will only be executed if the condition evaluates to true. Otherwise, it is skipped.
if statements allow us to execute specific code for certain conditions, rather than executing all code unconditionally. This gives us program control flow and the ability to make decisions in our code based on conditions.
The other options are incorrect:
to do something while a condition is true - This describes while loops, not if statements
to repeat something for a fixed number of times - This describes for loops, not if statements
So in summary, we use if statements in Java to conditionally execute blocks of code based on a boolean condition.
