Question

Show the merge of two unsorted arrays in Java
N size of array
M size of array

Answer 1

UnsortedArrayMerge.java

public class UnsortedArrayMerge {

public static void main(String[] args) {

int [] array1= {34,56,23,9,12,89,45};

int [] array2= {54,16,93,9,3,67};

int [] mergedArray = new int [array1.length + array2.length];

//Displaying array1

System.out.println("Array 1");

printArray(array1);

//Displaying array2

System.out.println("Array 1");

printArray(array2);

//adding all the elements nto single array

for(int i=0 ; i<array1.length ; i++){

mergedArray[i] = array1[i];

}

int count = array1.length;

for(int j=0 ; j<array2.length ; j++){

mergedArray[count] = array2[j];

count++;

}

//Displaying mergedArray

System.out.println("Merged Array");

printArray(mergedArray);

//calling sort

int [] sortedArray = sortArray(mergedArray);

//Displaying sortedArray

System.out.println("Sorted Array");

printArray(sortedArray);

}

//To sort array

public static int[] sortArray(int [] arrayTosort){

for (int i = 0; i < arrayTosort.length; i++) {

for (int j = i + 1; j < arrayTosort.length; j++) {

int temp = 0;

if (arrayTosort[i] > arrayTosort[j]) {

temp = arrayTosort[i];

arrayTosort[i] = arrayTosort[j];

arrayTosort[j] = temp;

}

}

}

return arrayTosort;

}

//To print array

public static void printArray(int [] arr){

for(int i=0 ; i<arr.length ; i++){

System.out.print( arr[i]+" ");

}

System.out.println();

}

}

Sample output:

Array 1
34 56 23 9 12 89 45
Array 1
54 16 93 9 3 67
Merged Array
34 56 23 9 12 89 45 54 16 93 9 3 67
Sorted Array
3 9 9 12 16 23 34 45 54 56 67 89 93
