Program to read and print string of one dim array in Java
Program to read and print string of one dim array in Java
In this tutorial, we will discuss the concept of Program to read and print string of one dim array in Java
In this topic, we are going to learn how to read and print Strings of one dimensional array in Java programming language using loops.
In this blog, We have already discuss that “What is an array“, type of arrays and how to access it(one dim, two dim and three dim arrays)
Arrays are the special type of variables to store Multiple type of values(int, string,char, etc)under the same name in the continuous memory location. we can be easily accessed using the indices(indexes)
Here,
- S1,S2,S3,S4 and S5 represent the string elements of the array
- 0,1,2,3 and 4 represent the index of the array which is used to access the array elements
- 1,2,3,4 and 5 represent the length of the array
Code to read and print String of one dim array
Read and print strings Using for loop
In this program, we are briefing input strings of an array and then print them using for loop in Java language
Program 1
//Java program to read and print elements a array using for
import java.util.Scanner;
class Array_Sin_Dim_String_For1{
public static void main (String args[]){
Scanner scan=new Scanner(System.in);
//create a scanner instance for receives input
// from the user - input from keyboard
System.out.print("Enter the Array length: ");
//Ask input from the user for array length
int len=scan.nextInt();
//Reading the input from the user
String arr[]=new String[len];
//declaration and creation of a string array
System.out.println("Enter the "+len+" String");
for(int i=0; i<len; i++){
arr[i]=scan.next();
//Reading the input from the user
}
System.out.println("\nEntered string are:");
for(int j=0; j<len; j++){
System.out.println(arr[j]);
}//display every array element
}
}
When the above code is executed, it produces the following result
Program 2
//Java program to read and print elements a array using for
import java.util.Scanner;
class Array_Sin_Dim_String_For2{
public static void main (String args[]){
Scanner scan=new Scanner(System.in);
//create a scanner instance for receives input
// from the user - input from keyboard
System.out.print("Enter the Array length: ");
//Ask input from the user for array length
int len=scan.nextInt();
//Reading the input from the user
String arr[]=new String[len];
//declaration and creation of an array
System.out.println("Enter the "+len+" String");
for(int i=0; i<len; i++){
System.out.print("[arr["+i+"]:");
arr[i]=scan.next();
//Reading the input from the user
}
System.out.println("\nEntered string are:");
for(int j=0; j<len; j++){
System.out.println("[arr["+j+"]:"+arr[j]);
}//display every array element
}
}
When the above code is executed, it produces the following result
Read and print strings Using while loop
In this program, we are briefing input strings of an array and then print them using while loop in Java language
Program 1
//Java program to read and print String an array using while
import java.util.Scanner;
class Array_Sin_Dim_String_While1{
public static void main (String args[]){
Scanner scan=new Scanner(System.in);
//create a scanner instance for receives input
// from the user - input from keyboard
System.out.print("Enter the Array length: ");
//Ask input from the user for array length
int len=scan.nextInt();
//Reading the input from the user
String arr[]=new String[len];
//declaration and creation of an array
System.out.println("Enter the "+len+" String");
int i=0;
while(i<len){
arr[i]=scan.next();
//Reading the input from the user
i++;
}
System.out.println("\nEntered string are:");
int j=0;
while(j<len){
System.out.println(arr[j]);
j++;
}//display every array element
}
}
When the above code is executed, it produces the following result
Program 2
//Java program to read and print String a array using while
import java.util.Scanner;
class Array_Sin_Dim_String_While2{
public static void main (String args[]){
Scanner scan=new Scanner(System.in);
//create a scanner instance for receives input
// from the user - input from keyboard
System.out.print("Enter the Array length: ");
//Ask input from the user for array length
int len=scan.nextInt();
//Reading the input from the user
String arr[]=new String[len];
//declaration and creation of an array
System.out.println("Enter the "+len+" String");
int i=0;
while(i<len){
System.out.print("[arr["+i+"]:");
arr[i]=scan.next();
//Reading the input from the user
i++;
}
System.out.println("\nEntered string are:");
int j=0;
while(j<len){
System.out.println("[arr["+j+"]:"+arr[j]);
j++;
}//display every array element
}
}
When the above code is executed, it produces the following result
Read and print strings Using do-while loop
In this program, we are briefing input strings of an array and then print them using do-while loop in Java language
Program 1
//Java program to read and print String an array using while
import java.util.Scanner;
class Array_Sin_Dim_String_DoWhile1{
public static void main (String args[]){
Scanner scan=new Scanner(System.in);
//create a scanner instance for receives input
// from the user - input from keyboard
System.out.print("Enter the Array length: ");
//Ask input from the user for array length
int len=scan.nextInt();
//Reading the input from the user
String arr[]=new String[len];
//declaration and creation of an array
System.out.println("Enter the "+len+" String");
int i=0;
do{
arr[i]=scan.next();
//Reading the input from the user
i++;
}while(i<len);
System.out.println("\nEntered string are:");
int j=0;
do{
System.out.println(arr[j]);
j++;
//display every array element
}while(j<len);
}
}
When the above code is executed, it produces the following result
Program 2
//Java program to read and print String a array using do-while
import java.util.Scanner;
class Array_Sin_Dim_String_DoWhile_2{
public static void main (String args[]){
Scanner scan=new Scanner(System.in);
//create a scanner instance for receives input
// from the user - input from keyboard
System.out.print("Enter the Array length: ");
//Ask input from the user for array length
int len=scan.nextInt();
//Reading the input from the user
String arr[]=new String[len];
//declaration and creation of an array
System.out.println("Enter the "+len+" String");
int i=0;
do{
System.out.print("[arr["+i+"]:");
arr[i]=scan.next();
//Reding the input from the user
i++;
}while(i<len);
System.out.println("\nEntered string are:");
int j=0;
do{
System.out.println("[arr["+j+"]:"+arr[j]);
j++;
}while(j<len);
//display every array element
}
}
When the above code is executed, it produces the following result
