What does this method do? In one short English sentence describe the task accomplished by this method. Write a static method named concatenate that takes two ArrayLists of Strings as a parameter and returns a new ArrayList of Strings that contains all of the elements of the first list followed by all of the elements of the second list.Explanation / Answer
Solution for the 6th Problem :-
Program :-
import java.util.*;
class StringArray
{
public void arrayString()
{
int size1,size2;
System.out.println("Enter how many strings you want in first array");
Scanner in=new Scanner(System.in);
size1=in.nextInt();
String[] str1=new String[size1];
System.out.println("Enter "+size1+" Strings");
for(int i=0;i<size1;i++)
{
str1[i]=in.next();
}
System.out.println("Enter how many strings you want in second array");
size2=in.nextInt();
String[] str2=new String[size2];
System.out.println("Enter "+size2+" Strings");
for(int i=0;i<size2;i++)
{
str2[i]=in.next();
}
String[] finalString=concatenate(str1,str2);
System.out.println("The all Strings are");
for(int i=0;i<finalString.length;i++)
{
System.out.println(finalString[i]);
}
}
public static String[] concatenate(String[] str1,String[] str2)
{
int size=str1.length+str2.length;
String[] str3=new String[size];
for(int i=0;i<str1.length;i++)
{
str3[i]=str1[i];
}
for(int i=str1.length,j=0;i<size;i++,j++)
{
str3[i]=str2[j];
}
return str3;
}
}
class FinalString
{
public static void main(String args[])
{
StringArray b=new StringArray();
b.arrayString();
}
}
Output
Enter how many strings you want in first array
2
Enter 2 Strings
hello
how
Enter how many strings you want in second array
3
Enter 3 Strings
are
you
now
The all Strings are
hello
how
are
you
now
