Question: Write a method called wordWrap that accepts a Scanner representing an input file as its parameter and outputs each line of the file to the console, word-wrapping all lines that are longer than 60 characters. For example, if a line contains 112 characters, the method should replace it with two lines: one containing the first 60 characters and another containing the final 52 characters. A line containing 217 characters should be wrapped into four lines: three of length 60 and a final line of length 37.
My code:
public void wordWrap(Scanner input) {
while(input.hasNextLine()){
String line=input.nextLine();
Scanner scan=new Scanner(line);
if(scan.hasNext()){
superOuter:
while(line.length()>0){
for(int i=0;i<line.length();i++){
if( i<60 && line.length()>59){
System.out.print(line.charAt(i));
}
//FINISH OFF LINE<=60 characters here
else if(line.length()<59){
for(int j=0;j<line.length();j++){
System.out.print(line.charAt(j));
}
System.out.println();
break superOuter;
}
else{
System.out.println();
line=line.substring(i);
break ;
}
}
}
}
else{
System.out.println();
}
}
}
Problem in the output:
Expected output:
