The fill(object[] a, int fromIndex, int toIndex, object val) method of the class java.util.Arrays assign the specified Object reference to each element of the specified range of the specified array of objects. The range to be filled extends from index fromIndex, inclusive, to index toIndex, exclusive. (If fromIndex==toIndex, the range to be filled is empty)Exampleimport java.util.Arrays; public class ArrayDemo { public static void main(String[] args) { Object arr[] = new Object[] {1.2, 5.6, 3.4, 2.9, 9.7}; System.out.println("Actual values: "); for (Object value : arr) { System.out.println("Value ...

The fill(Object[] a, Object val) method of the java.util.Arrays class assigns the specified Object reference to each element of the specified array of Objects.Exampleimport java.util.Arrays; public class ArrayDemo { public static void main(String[] args) { Object arr[] = new Object[] {10.5, 5.6, 4.7, 2.9, 9.7}; System.out.println("Actual values: "); for (Object value : arr) { System.out.println("Value = " + value); } Arrays.fill(arr, 12.2); System.out.println("New values after using fill() method: "); for (Object value : arr) { System.out.println("Value = " + value); } } }OutputActual values: Value = 10.5 Value = 5.6 Value = 4.7 Value = 2.9 Value = 9.7 New values after using fill() method: Value = 12.2 Value = 12.2 Value = 12.2 Value = 12.2 Value = 12.2

The fill(int[] a, int fromIndex, int toIndex, int val) method of the java.util.Arrays class assigns the specified int value to each element of the specified range of the specified array of integers. The range to be filled extends from index fromIndex, inclusive, to index toIndex, exclusive.(If fromIndex==toIndex, the range to be filled is empty.)Exampleimport java.util.Arrays; public class ArrayDemo { public static void main(String[] args) { int arr[] = new int[] {1, 6, 3, 2, 9}; System.out.println("Actual values: "); for (int value : arr) { System.out.println("Value = ...

The toString(Object[] a) method of the java.util.Arrays class returns a string representation of the contents of the specified Object array. If the array contains other arrays of elements, they are converted to strings by the Object.toString() method inherited from Object, which describes their identities rather than their contents. Example import java.util.Arrays; public class ArrayDemo { public static void main(String[] args) { Object[] ob1 = new Object[] { 10, 20 }; System.out.println("The array is:"); for (Object number ...

The toString(int[]) method of the class java.util.Arrays return a string representation of the contents of the specified int array. The string representation consists of a list of the array's elements, enclosed in square brackets ("[]"). Adjacent elements are separated by the characters ", " (a comma followed by a space).Exampleimport java.util.Arrays; public class ArrayDemo { public static void main(String[] args) { int[] i1 = new int[] { 33, 12, 98 }; System.out.println("The array is:"); for (int number : i1) { System.out.println("Number = " + number); ...

Operator precedence determines the grouping of terms in an expression. This affects how an expression is evaluated. Certain operators have higher precedence than others; for example, the multiplication operator has higher precedence than the addition operator.Here, operators with the highest precedence appear at the top of the table, those with the lowest appear at the bottom. Within an expression, higher precedence operators will be evaluated first.CategoryOperatorAssociativityPostfix>() [] .

The java.util.Arrays.sort(Object[] a, int fromIndex, int toIndex) method sorts the specified range of the specified array of objects into ascending order, according to the natural ordering of its elements. The range to be sorted extends from index fromIndex, inclusive, to index toIndex, exclusive.Exampleimport java.util.Arrays; public class ArrayDemo { public static void main(String[] args) { Object ob[] = {27, 11, 5, 44}; for (Object number : ob) { System.out.println("Number = " + number); } Arrays.sort(ob, 1, 3); System.out.println("Object array ...

The sort(int[] a, int fromIndex, int toIndex) method of the java.util.Arrays class sorts the specified range of the specified array of integer value into ascending numerical order. The range to be sorted extends from index fromIndex, inclusive, to index toIndex, exclusive.Exampleimport java.util.Arrays; public class ArrayDemo { public static void main(String[] args) { int iArr[] = {3, 1, 2, 18, 10}; for (int number : iArr) { System.out.println("Number = " + number); } Arrays.sort(iArr, 0, 3); System.out.println("int array with some ...
