greatest of three in java

To find the greatest of three values in Java, you can use a simple if statement to compare the values and return the maximum one.

Here's an example of how you can do this:

int a = 5;
int b = 10;
int c = 15;

int max = a;
if (b > max) {
    max = b;
}
if (c > max) {
    max = c;
}

System.out.println("The greatest of the three values is " + max);

This code will print "The greatest of the three values is 15".

You can also use the Math.max() method to find the maximum of three values:

int a = 5;
int b = 10;
int c = 15;

int max = Math.max(a, Math.max(b, c));

System.out.println("The greatest of the three values is " + max);

This code will also print "The greatest of the three values is 15".

Note that these examples assume that the values are of type int. If the values are of a different type, such as double or String, you will need to use a different approach to compare the values. For example, you can use the compareTo() method for String objects or the Double.compare() method for Double objects.
