Following is the required program.ExampleLive Demopublic class Tester {    public static void main(String args[]) {       int i, m = 0, flag = 0;       int n = 41;// it is the number to be checked       m = n / 2;       if (n == 0 || n == 1) {          System.out.println(n + " not a prime number");       } else {          for (i = 2; i

Following is the required program.ExampleLive Demopublic class Tester {    static int n1 = 0, n2 = 1, n3 = 0;    static void fibbonacci(int count) {       if (count > 0) {          n3 = n1 + n2;          n1 = n2;          n2 = n3;          System.out.print(" " + n3);          fibbonacci(count - 1);       }    }    public static void main(String args[]) {       int count = 5;       System.out.print(n1 + " " + n2);       fibbonacci(count - 2);    } }Output0 1 1 2 3

Following is the required program.ExampleLive Demopublic class Tester {    public static void main(String args[]) {        int n1 = 0, n2 = 1, n3, i, max = 5;        System.out.print(n1 + " " + n2);        for (i = 2; i < max; ++i) {           n3 = n1 + n2;           System.out.print(" " + n3);           n1 = n2;           n2 = n3;        }     }  }Output0 1 1 2 3

Following example showcases labels 'first', 'second' before a for statement and use the break/continue controls to jump to that label. See the example below.ExampleLive Demopublic class Tester {    public static void main(String args[]) {       first:          for (int i = 0; i < 3; i++) {             for (int j = 0; j< 3; j++){                if(i == 1){                   continue first;                }         ...

Java programming language provides following types of decision making or branching statements.Java programming language provides following types of decision making statements.Sr.No.Statement & Description1if statementAn if statement consists of a boolean expression followed by one or more statements.2if...else statementAn if statement can be followed by an optional else statement, which executes when the boolean expression is false.3nested if statementYou can use one if or else if statement inside another if or else if statement(s).4switch statementA switch statement allows a variable to be tested for equality against a list of values.

ExampleFollowing is the required program −Live Demopublic class Tester {    public static void main(String args[]) {       int i = 0;       do {          i++;          System.out.println(i);       }while (true);    } }The output will keep printing numbers in sequential order.

Yes. Following while loop is a valid statement and causes an infinite loop.while(true);

Following program is using labeled for loops.ExampleLive Demopublic class Tester {    public static void main(String args[]) {             first:          for (int i = 0; i < 3; i++) {             for (int j = 0; j< 3; j++){                if(i == 1){                   continue first;                }                      System.out.print(" [i = " + i + ", ...
