If Statements for Conditional Logic

Conditional statements let you control the flow of your program based on different conditions. Here’s how to use if statements to evaluate and act on various conditions in Java.

Equals To

To check if two values are equal, use the double equals sign ==. For all of these examples lets make an int called x and assign the value 50 to it.

int x = 50;
if (x == 50) {
    System.out.println("x is equal to 50");
}

Greater Than

Use > to check if a value is greater than another.

if (x > 50) {
    System.out.println("x is greater than 50");
}

Less Than

Use < to check if a value is less than another.

if (x < 50) {
    System.out.println("x is less than 50");
}

Greater or Equals To

Use >= to check if a value is either greater than or equal to another.

if (x >= 50) {
    System.out.println("x is greater than or equal to 50");
}
