Getting String Representation of a Positive int Value Example

The following example shows the usage of Integer toString() method to get the string representation of the specified int value. We've created a int variable and assigned it a positive int value. Then using toString() method, we're printing the result.

package com.tutorialspoint;
public class IntegerDemo {
   public static void main(String[] args) {
      int i = 170;
      System.out.println("Number = " + i);
    
      /* returns the string representation of the given number */
      System.out.println("toString = " + Integer.toString(i));
   }
}

Output

Let us compile and run the above program, this will produce the following result −

Number = 170
toString = 170

Getting String Representation of a Negative int Value Example

The following example shows the usage of Integer toString() method to get the string representation of the specified int value. We've created a int variable and assigned it a negative int value. Then using toString() method, we're printing the result.

package com.tutorialspoint;
public class IntegerDemo {
   public static void main(String[] args) {
      int i = -170;
      System.out.println("Number = " + i);
    
      /* returns the string representation of the given number */
      System.out.println("toString = " + Integer.toString(i));
   }
}

Output

Let us compile and run the above program, this will produce the following result −

Number = -170
toString = -170

Getting String Representation of a Positive Zero Value Example

The following example shows the usage of Integer toString() method to get the string representation of the specified int value. We've created a int variable and assigned it a zero value. Then using toString() method, we're printing the result.

package com.tutorialspoint;
public class IntegerDemo {
   public static void main(String[] args) {
      int i = 0;
      System.out.println("Number = " + i);
    
      /* returns the string representation of the given number */
      System.out.println("toString = " + Integer.toString(i));
   }
}

Output

Let us compile and run the above program, this will produce the following result −

Number = 0
toString = 0
