Scanner s = new Scanner(System.in);
System.out.println("Enter any Sentence");
String ss = s.nextLine();
String[ ] a = ss.split(" ");
String res = "";
for(int i = 0;i<a.length;i++)
{
String str = a[i];
for(int j = 0;j<str.length();j++)
{
int ch = str.charAt(j);
if(ch<=90 && ch>=65)
{
res+ = str.charAt(j)+" ";
}
}

Write a program which accepts 2 strings from the user and performs string concatenation in JAVA

Write a program which accepts 2 strings from the user and performs the following operation on it.

Example1:

String1 = "JAVA"
String2 = "PYTHON"
String3 must be "JAVANOHTYP"

Example2:

String1 = "Vignesh"
String2 = "Sundeep"
String3 must be "VigneshpeednuS"

Both strings must be concatenated but after reversing the second string (as shown in string3 above).

Program:

import java.util.Scanner;

public class String_Program {
public static void main(String[ ] args) {
Scanner s = new Scanner(System.in);
System.out.println("Enter any two strings: ");
String s1 = s.next();
String s2 = s.next();
StringBuffer sb = new StringBuffer(s2);
sb.reverse( );
System.out.println(s1+sb);
}
}

Input/Output:

Enter any two strings:
Raju
Ramana
RajuanamaR

Program:

import java.util.Arrays;
import java.util.Scanner;

public class String_Program{
public static boolean ISin(String str, char c) {
for (int i = 0; i < str.length(); i++) {
if (str.charAt(i) == c) {
return true;
}
}
return false;
}
public static void main(String[] args) {
Scanner s = new Scanner(System.in);
System.out.println("Enter 10 digit number: ");
long n = s.nextLong();
String str = n + "";
String res = "";
String no[] = new String[] { "ZERO", "ONE", "TWO", "THREE", "FOUR", "FIVE", "SIX", "SEVEN", "EIGHT", "NINE" };
if (str.length( ) < 10 || str.length( ) > 10) {
System.out.println("Invalid Input");
} else {
for (int i = 0; i < str.length(); i++) {
res = res + no[Integer.parseInt(str.charAt(i) + "")];
}
}
String temp = "";
for (int i = 0; i < res.length(); i++) {
if (!ISin(temp, res.charAt(i))) {
temp = temp + res.charAt(i);
}
}
String r[] = new String[temp.length()];
for (int i = 0; i < r.length; i++) {
r[i] = temp.charAt(i) + "";
}
String rr = "";
Arrays.sort(r);
for (int i = 0; i < r.length; i++) {
rr += r[i];
}
System.out.println(rr);

}
}

Input/Output:

Enter 10 digit number:
1234567812
