For eg.
Input: 1st String - Hello World
2nd String - Welcome to Java
Output: Hello World Welcome to Java
Program 1:
<![CDATA[import java.util.*;
class StringConcat{
public static void main(String[] args){
int length1,length2;
String word1,word2;
char[] cword1,cword2,finalword;
Scanner sc=new Scanner(System.in);
word1=sc.nextLine();
word2=sc.nextLine();
cword1=word1.toCharArray();
cword2=word2.toCharArray();
length1=word1.length();
length2=word2.length();
finalword=new char[length1+length2];
for(int k=0;k<length1;k++){
finalword[k]=cword1[k];
}
for(int i=0,k=length1;k<(length1+length2);k++,i++){
finalword[k]=cword2[i];
}
for(char word:finalword)
System.out.print(word);
}
}
]]>
Program 2:
<![CDATA[class ConcatenateString
{
public static void main(String args[])
{
String string1,string2;
Scanner sc = new Scanner(System.in);
System.out.println("Enter the 1st string");
string1=sc.nextLine();
System.out.println("Enter the 2nd string");
string2=sc.nextLine();
System.out.println("Concatenated String is ");
System.out.println(string1+string2);
}
}
