import java.util.Scanner;
public class StringReadAndWrite {
public static void main(String[] args) {
Scanner sc=new Scanner(System.in);
System.out.println("enter the length of String array");
int n=sc.nextInt();
String[] sarray=new String[n];
for(int i=0;i<n;i++){
System.out.println("enter the "+(i+1)+" String :");
sarray[i]=sc.next();
}
System.out.println("Strings Entered by user:");
for(String s:sarray){
System.out.println(s);
}
}
}

To read into string array and then read the populated array you could use:
要读入字符串数组，然后读取填充的数组，您可以使用：
public static void main(String [] args){
// to populate string array`enter code here`
Scanner sc = new Scanner(System.in);
int length = 10, pos = -1;
String arr[] = new String[length];
while(++pos < length){
System.out.print("Enter string : ");
arr[pos] = sc.nextLine();
}
// to read the already populated string array1
for(String s: arr){
System.out.println(s);
}
}

Program to read specific number of elements from the console and write them on the console.
程序从控制台读取特定数量的元素并将它们写入控制台。
public class Test {
public static void main(String args[]) {
System.out.println("Enter string array size");
Scanner in = new Scanner(System.in);
int i = in.nextInt();
String[] arr = new String[i];
for (int j = 0; j < i; j++) {
System.out.println("Enter next element");
arr[j] = in.next();
}
for (String s : arr) {
System.out.println("Next element[" + s+"]");
}
}
}
