Nested if statement?

1. If statement in the if statement

// can be multi-if statements for more specific conditions and results

int temp = 20;
boolean isRain = true;

if (temp < 10) {
    if (isRain) {
    	System.out.println("Cold and rainy! Be careful!");
    } else {
    	System.out.println("It's cold outside!";
    } 
} else {
    System.out.println("It's such a good day, mate!");
} // end of if
