The checkedAdd(int a, int b) is a method of Guava’s IntMath Class which accepts two parameters a and b, and returns their sum.
Syntax:
public static int checkedAdd(int a, int b)
Parameters: The method accepts two int values a and b and computes their sum.
Return Value: The method returns the sum of int values passed to it, provided it does not overflow.
Exceptions: The method checkedAdd(int a, int b) throws ArithmeticException if the sum i.e, (a – b) overflows in signed int arithmetic.
Below examples illustrate the implementation of above method:
Example 1:
// Java code to show implementation of // checkedAdd(int a, int b) method // of Guava's IntMath class import java.math.RoundingMode;
import com.google.common.math.IntMath;
class GFG {
// Driver code
public static void main(String args[])
{
int a1 = 25 ;
int b1 = 36 ;
// Using checkedAdd(int a, int b)
// method of Guava's IntMath class
int ans1 = IntMath.checkedAdd(a1, b1);
System.out.println( "Sum of " + a1 + " and "
+ b1 + " is: " + ans1);
int a2 = 150 ;
int b2 = 667 ;
// Using checkedAdd(int a, int b)
// method of Guava's IntMath class
int ans2 = IntMath.checkedAdd(a2, b2);
System.out.println( "Sum of " + a2 + " and "
+ b2 + " is: " + ans2);
}
} |
Output:
Sum of 25 and 36 is: 61 Sum of 150 and 667 is: 817
Example 2:
// Java code to show implementation of // checkedAdd(int a, int b) method // of Guava's IntMath class import java.math.RoundingMode;
import com.google.common.math.IntMath;
class GFG {
static int findDiff( int a, int b)
{
try {
// Using checkedAdd(int a, int b) method
// of Guava's IntMath class
// This should throw "ArithmeticException"
// as the sum overflows in signed
// int arithmetic
int ans = IntMath.checkedAdd(a, b);
// Return the answer
return ans;
}
catch (Exception e) {
System.out.println(e);
return - 1 ;
}
}
// Driver code
public static void main(String args[])
{
int a = Integer.MIN_VALUE;
int b = 452 ;
try {
// Function calling
findDiff(a, b);
}
catch (Exception e) {
System.out.println(e);
}
}

Output:
