So I need to write a method which accepts one String object and one integer and repeat that string times integer.
For example: repeat("ya",3) need to display "yayaya" I wrote down this code but it prints one under the other. Could you guys help me please?
public class Exercise{
public static void main(String[] args){
repeat("ya", 5);
}
public static void repeat(String str, int times){
for(int i = 0;i < times;i++){
System.out.println(str);
}
}
}
You are printing it on new line, so try using this :
public static void repeat(String str, int times){
for(int i = 0;i < times;i++){
System.out.print(str);
}
}
You're using System.out.println which prints what is contained followed by a new line. You want to change this to:
public class Exercise{
public static void main(String[] args){
repeat("ya", 5);
}
public static void repeat(String str, int times){
for(int i = 0; i < times; i++){
System.out.print(str);
}
// This is only if you want a new line after the repeated string prints.
System.out.print("\n");
}
}
Change System.out.println() to System.out.print().
Example using println():
System.out.println("hello");// contains \n after the string
System.out.println("hello");
Output:
hello
hello
Example using print():
System.out.print("hello");
System.out.print("hello");
Output:
hellohello
Try to understand the diference.
Your example using recursion/without loop:
public class Repeat {
StringBuilder builder = new StringBuilder();
public static void main(String[] args) {
Repeat rep = new Repeat();
rep.repeat("hello", 10);
System.out.println(rep.builder);
}
public void repeat(String str, int times){
if(times == 0){
return;
}
builder.append(str);
repeat(str, --times);
}
}
public class pgm {
public static void main(String[] args){
repeat("ya", 5);
}
public static void repeat(String str, int times){
for(int i = 0;i < times;i++){
System.out.print(str);
}
}
}
System.out.printlntoSystem.out.print(and add aSystem.out.println();after your loop).
