I'm a beginner and I want to output the following using a for loop and subscript and I'm not sure.
output:
Jamaica
amaica
maica
aica
ica
ca
a
What can I do, in order to achieve this output?
First: You need to loop for generating n
line which is the length of array.
Second: You need to print the spaces with is same value as row - 1
number of times.
Second: You need to print character start from row - 1
number to the length of the string.
And the final solution will be:
public class MyClass {
public static void printStr(String str) {
int i,j;
for (i = 0; i < str.length();i++) {
for(j = 0; j < i; j++) {
System.out.print(" ");
}
for(j = i; j < str.length();j++) {
System.out.print(str.charAt(j));
}
System.out.println("");
}
}
public static void main(String args[]) {
MyClass.printStr("Jamaica");
}
}
I would use two regular expressions , the first to terminate the loop when the String
is filled with white space. The second to replace the first non-white space character with a white space in the loop body (after printing the current String
value). And, if it's possible the String
might be empty you should guard against that. Like,
String s = "Jamaica";
if (!s.isEmpty()) {
while (!s.matches("\\s+")) {
System.out.println(s);
s = s.replaceFirst("\\S", " ");
}
}
Outputs (as requested)
Jamaica
amaica
maica
aica
ica
ca
a
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
String s = scan.next(); //input through scanner class
int len = s.length();
for(int i=0;i<len;i++){
for(int j=0;j<i;j++){
System.out.print(" ");
}
for(int j=i;j<len;j++){
System.out.print(s.charAt(j));
}
System.out.println("");
}
}
Hopefully that helps
Try following code:
StringBuilder country = new StringBuilder("Jamaica");
for(int i=0; i< country.length();i++){
if(i > 0)
{
for(int j=0;j<i;j++){
country.setCharAt(j,' ');
}
}
System.out.println(country);
}
