+## Problem Statement
+Write a Java program to count the number of set bits (1s) in the binary representation of a given non-negative integer.
+
+### Input
+- A single integer `n` where `0 <= n <= 10^9`.
+
+### Output
+- The number of set bits (1s) in the binary representation of the integer.
+
+### Example
+
+#### Example 1:
+**Input**:  
+`5`
+
+**Output**:  
+`2`
+
+**Explanation**:  
+Binary representation of 5 is `101`, which has 2 set bits.
+
+#### Example 2:
+**Input**:  
+`10`
+
+**Output**:  
+`2`
+
+**Explanation**:  
+Binary representation of 10 is `1010`, which has 2 set bits.
+
+#### Example 3:
+**Input**:  
+`0`
+
+**Output**:  
+`0`
+
+**Explanation**:  
+Binary representation of 0 is `0`, which has no set bits.
+
+### Constraints
+- `0 <= n <= 10^9`
