Java rotates the matrix 45-degree output

For example:

A B C D E F G H I J K L M N O P Q R S T U V W X Y     E       D J     C I O   B H N T A G M S Y F L R X   K Q W     P V       U    

Ideas such as:
Outside the diamond is a space, within the diamond (can use function to judge) There are two kinds of points, one is a character, one is a space
It can be found that there is a character position (col-row)%2 = = 0; next look for a 45 degree diamond and rectangle correspondence, row ' = (col-row)/2, col ' =col-row '

The complete code is as follows:

 Public  class printmatrixtrans45degree {     Public Static void Main(string[] args) {System.out.println ("Hello world!");intC=0;Char[] arr =New Char[5][5]; for(inti =0; I <5; i++) { for(intj =0; J <5; J + +) {arr[i][j]= (Char)(' A '+ c);            C + +; }        } for(inti =0; I <5; i++) { for(intj =0; J <5; J + +) {System.out.print (arr[i][j]+" ");        } System.out.println (); } for(inti =4; I >=-4; i--) {introw =0;intCol =0; for(intj =0; J <=8; J + +) {if(Isarea (I,J)) {if((j-i)%2==0){//Print lettersrow = (j-i)/2;                        col = J-row;                    System.out.print (Arr[row][col]); }Else{System.out.print (" "); }                                   }Else{//Print spaceSystem.out.print (" ");        }} System.out.println (); }    } Public Static Boolean Isarea(intRow,intCol) {if(Row <= col && Row >= Col-8&& row >=-col && row <=-col +8){//system.out.println ("(" +row+ "," +col+ ")");            return true; }return false; }}
