To compare two Byte Arrays, use the Arrays.equals() method. Here we have declared and initialized a total of 4 arrays.byte[] arr1 = new byte[] { 11, 13, 30, 45, 77, 89 }; byte[] arr2 = new byte[] { 12, 13, 34, 87, 99, 33}; byte[] arr3 = new byte[] { 11, 13, 30, 45, 77, 89 }; byte[] arr4 = new byte[] { 13, 16, 56, 78, 98, 99 };Now, using the Arrays.equals() method, we will be compare two arrays.Arrays.equals(arr1, arr2);In the same way, other arrays would be compared one by one.Let us see the complete example to compare two ...

In Java, there are different ways to convert byte to string.Using toString() method, you can easily convert byte to string as shown below −Example Live Demopublic class Demo {    public static void main(String[] args) {       byte res = 87;       // byte to string       System.out.println(Byte.toString(res));    } }Output87In the above example, we have taken a byte value.byte res = 87;With that, to convert to string, the method toString() is used as shown below −Byte.toString(res);Let us see another example to convert byte to string.Example Live Demopublic class Demo {    public static void main(String[] ...

The following is an example displaying the minimum of three integer values.Example Live Demopublic class Demo {    public static void main(String[] args) {       int val1 = 99;       int val2 = 87;       int val3 = 130;       System.out.println("Number 1 = "+val1);       System.out.println("Number 2 = "+val2);       System.out.println("Number 3 = "+val3);       if (val2 < val1) {          val1 = val2;       }       if (val3 < val1) {          val1 = val3;   ...

The following is an example displaying the maximum of three integer values.Example Live Demopublic class Demo {    public static void main(String[] args) {       int val1 = 10;       int val2 = 20;       int val3 = 30;       System.out.println("Number 1 = "+val1);       System.out.println("Number 2 = "+val2);       System.out.println("Number 3 = "+val3);       if (val2 > val1) {          val1 = val2;       }       if (val3 > val1) {          val1 = val3;   ...

To get the minimum value of datatype int in Java, use the following −Integer.MIN_VALUETo get the maximum value of datatype int in Java, use the following −Integer.MAX_VALUELet us now implement this in our example.Example Live Demopublic class Demo {    public static void main(String[] args) {       int val1 = 20;       int val2 = 3000;       System.out.println("Value1: "+val1);       System.out.println("Value2: "+val2);       System.out.println("Maximum value: "+Integer.MIN_VALUE);       System.out.println("Minimum value: "+Integer.MAX_VALUE);    } }OutputValue1: 20 Value2: 3000 Maximum value: -2147483648 Minimum value: 2147483647

To check for Integer overflow, we need to check the Integer.MAX_VALUE, which is the maximum value of an integer in Java.Let us see an example wherein integers are added and if the sum is more than the Integer.MAX_VALUE, then an exception is thrown.Example Live Demopublic class Demo {    public static void main(String[] args) {       int val1 = 9898989;       int val2 = 6789054;       System.out.println("Value1: "+val1);       System.out.println("Value2: "+val2);       long sum = (long)val1 + (long)val2;       if (sum > Integer.MAX_VALUE) {          throw ...

To convert decimal to binary, Java has a method Integer.toBinaryString(). The method returns a string representation of the integer argument as an unsigned integer in base 2.Let us first declare and initialize an integer variable.int dec = 25;Convert it to binary.String bin = Integer.toBinaryString(dec);Now display the “bin” string, which consists of the Binary value. Here is the complete example.Example Live Demopublic class Demo {    public static void main( String args[] ) {       int dec = 25;       // converting to binary and representing it in a string       String bin = Integer.toBinaryString(dec);       System.out.println(bin);    } }Output11001

To perform XOR on a set of Booleans, firstly let us consider the following Boolean array.boolean[] arr = { true, true, false };Let us now create a nested loop and within that perform XOR operation.for (boolean one : arr) {    for (boolean two: arr) {       // XOR       boolean res = one ^ two;    } }Here is the entire example to displayXOR on a set of Booleans.Example Live Demopublic class Demo {    public static void main(String[] args) {       // boolean array       boolean[] arr = { true, true, ...

To convert int to boolean, let us first take the following int.int one = 1; int two = 1; int three = 0;We have nested if-else statement to display the true or false values. Here, the value “one” is the same as “two” i.e. 1; therefore, the following works −else if (one.equals(two)) {    System.out.println(true); }The above display “true” and in this way we converted int to boolean.Let us now see the complete example to learn how to convert int to Boolean.Example Live Demopublic class Demo {    public static void main(String[] args) {       int one = 1; ...

To convert integer to boolean, firstly let us initialize an integer.int val = 100;Now we will declare a variable with primitive boolean. While declaration, we will initialize it with the val value comparing it with an integer using the == operator. If the value matches, the value “True” is returned, else “False” is returned.boolean bool = (val == 100);Let us now see the complete example displaying how to convert integer to boolean.Example Live Demopublic class Demo {    public static void main(String[] args) {       int val = 100;       System.out.println("Integer: "+val);       boolean bool ...
