Bad operand types for binary operator: How to solve it in Java

Java is a general-purpose, object-oriented programming language based on classes that is designed to have fewer implementation requirements. Furthermore, it is a computer platform for the development of applications. As a result, Java is quick, secure, and trustworthy. Additionally, it’s commonly used in laptops, data centers, game consoles, scientific supercomputers, cell phones,… Therefore, in this blog, ArrowHiTech will guide you how to solve Bad operand types for binary operator ‘&&’ and ‘&’  in Java. So let’s explore now.

Bad operand types for binary operator &

For example: Producing the error by using if condition

Because this error is easily produced by using & in the if condition, as seen below:

public class JavaHungry {

    public static void main(String args[]) {

      int x=100;

      // Using & operator in if condition

      if(x & 100 == 1)

      {

          System.out.println(“inside if condition”);

      }

      else 

      {

          System.out.println(“inside else condition”);

      }

    }

}

Output:

bad operand types for binary operator

Explanation:

Because the problem is caused by the order in which operators are executed. Additionally, the operator takes precedence over the & operator. As a result, 100==1 will be computed first. Moreover, the boolean value will be returned. So you’ll see that the & operator now has two operands: one is an int and the other is a boolean. Because both operands are different, the compilation error mentioned above will occur.

Solution:

The above compilation error can be fixed by properly using parenthesis.

public class JavaHungry {

    public static void main(String args[]) {

      int x=100;

      // Using & operator in if condition

    if((x & 100) == 1)

      {

          System.out.println(“inside if condition”);

      }

    else 

      {

          System.out.println(“inside else condition”);

      }

    }

}

Output:

inside else condition

Bad operand types for binary operator ‘&&’

For example: Producing the error by using if condition

We’ll make the error first, then go on to the solution, just like we did before.

public class JavaHungry {

    public static void main(String args[]) {

      int x=1000;

      if( (x > 100) && (x/2))

      {

          System.out.println(x);

      }

    }

}

OutputBad operand types for binary operator ‘&&’

bad operand types for binary operator

Explanation:

This issue occurs because (x/2) is a numeric expression that returns an integer value. Therefore, the logical AND operator is known as &&. As a result, it anticipates boolean values on both sides. Moreover, the && operator has two operands in the if condition: one is boolean and the other is int. So the compilation error mentions the same thing.

Solution of Bad operand types for binary operator ‘&&’

Therefore, converting the second operand to a boolean type will fix the compilation error mentioned above.

public class JavaHungry {

    public static void main(String args[]) {

      int x=1000;     

    if( (x > 100) && (x/2 > 0))

      {

          System.out.println(x);

      }

    }

}

Output:

1000
