*** str+=i; case 2: avg= sum/num; { For example, For example, // print array elements class Main { public static void main(String[] args) { // create an array int[] numbers = {3, 7, 5, -5}; // iterating through the array for (int number: numbers) { System.out.println(number); } } } Write a program to find the value of one number raised to the power of another. 20. case 3: } * * package test_projects; It also accepts an integer array. This solution works with 2 for statements: Loops in Java¶. Abstract class. This program is a good exercise for mastering loops e.g. for(j=1;j<=i;j++) The below method can be used to get the min value of an array. /* for (int i=1; i<=num;i++) There is no time limit to complete the quiz. The user should supply x } { case 1: Write a Java program than read an integer and calculate the sum of its digits and write the number of each digit of the sum in English. for(j=65;j<=i;j++) } Know data-types. } Loop Statements In Java. The Java for loop is used to iterate a part of the program several times. + x5/5! // Printing Symbols All these programs are given with the maximum examples and output. { import java.util.Scanner; String s,l; The course is designed to give you a head start into Java programming and train you for both core and advanced Java concepts along with various Java frameworks like Hibernate & Spring.     32123 //////////////////////////////////////////////////////////////////////// please i want the solution quickly ): Rita, you can use this code: // Printing Symbols System.out.print("\u001B[35m" +(char) k + " = " + "\u001B[34m" +k + " ; " ); /* { Write a program to enter the numbers till the user wants and at the end it should display the count of positive, negative and zeros entered. } // Default Text { } for (int j = 8 - cpt; j > 0 ; j--){ Following is an example program that nests the Java for loops: /* Java Program Example - Java Nested Loops */ public class JavaProgram { public static void main (String args []) { int i, j; for (i=0; i<10; i++) { for (j=0; jarr[i]) min=arr[i]; * * System.out.println(""); If so, the loop should repeat; otherwise it should terminate. for(k=65;k<91;k++) Write a program to find the factorial value of any number entered through the keyboard.
