4-3. Comparing int Values
Problem

You need to compare two or more int values.

Solution #1

Use the comparison operators to compare integer values against one another. In the fol-
lowing example, three int values are compared against each other, demonstrating
various comparison operators:

int int1 = 1;
int int2 = 10;
int int3 = -5;

System.out.println(int1 == int2); // Result: false

System.out.println(int3 == int1); // Result: false

System.out.println(int1 == int1); // Result: true

System.out.println(int1 > int3); // Result: true

System.out.println(int2 < int3); // Result: false

As you can see, comparison operators will generate a Boolean result.
