数组越界？ 带字符串分割

Question

Array out of bounds ? i'm trying to perform the output in the picture:

Using this INPUT "JAVA IS A PROGRAMMING LANGUAGE"

This is my code so far

import java.util.Scanner;
public class Main
{
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        System.out.print("Input Phrase:");
        String s = in.nextLine();

        String[] word=s.split(" ");
        String rts=" ";

        for(int i=0;i<word.length;i++){
            if(word[i].length()>=rts.length()){
                rts=word[i];
            }
        }

        int thisislength = rts.length();

        for (int a = 0; a < thisislength ;a++ ) {
            for (int b = 0; b < word.length ;b++ ) {
                System.out.print(word[b].charAt(a)+" ");  
            }
            System.out.println();
        }
    }
}

When the second word reaches its last letter it doesn't continue the for loop, is there any way to continue the loop even if the second word reaches its max length.

Answer 1

< should have been <= . Reversing left and right hand sides makes it more readably I think.

    for (int a = 0; a < thisislength; a++) {
        System.out.printf("%3d ", a+1);
        for (int b = 0; b < word.length; b++) {
            if (a >= word[b].length()) {
                System.out.print(' ');
            } else {
                System.out.print(word[b].charAt(a));  
            }
            System.out.print(' ');
        }
        System.out.println();
    }

Or instead of the if-else statement:

        for (String w : word) {
            System.out.print(a >= w.length() ? ' ' : w.charAt(a));  
        }

This gives the result you want:

for (int a = 0; a < thisislength ;a++ ){
    for (int b = 0; b < word.length ;b++ ){
        if(word[b].length() < a + 1){
            System.out.print("  ");
        }else{
            System.out.print(word[b].charAt(a) + " ");
        }
    }
    System.out.println();
}

This line was changed:
if(word[b].length() < a + 1) and not if(word[b].length() < a)
and 2 spaces print in the if statement

TRY THIS SOLUTION HOPE IT WILL HELP YOU :

import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;
public class Main
{
    public static void main(String[] args) {

        // GET VALUE FROM THE CONSOLE
        Scanner in = new Scanner(System.in);
        System.out.print("Input Phrase:");
        String s = in.nextLine();

        // SPLIT STRING TO WORDS
        String[] words = s.split(" ");

        // CREATE A LIST OF CHAR_ARRAY CALLED : matrix
        List<char[]> matrix = new ArrayList<char[]>();

        // REFERENCE THE LARGEST WORD IN WORDS ARRAY EX : PROGRAMMING IS THE LARGEST 
        int max = 0;

        // FILL OUR LIST OF ARRAY OF CHARS
        for (int b = 0; b < words.length ;b++ ) {
            char[] chars =  words[b].toCharArray();
            max = (chars.length >= max)? chars.length :  max ;
            matrix.add( chars );
        }

        // PRINT OUR CHAR
        for (int a = 0; a < max ;a++ ) {

            for (int b = 0; b < words.length ;b++ ) {

                if(a < matrix.get(b).length) {
                    System.out.print(matrix.get(b)[a]);
                    System.out.print(" ");
                }else {
                    System.out.print(" ");
                    System.out.print(" ");
                }

            }

            System.out.println("");

        }

    }
}
