Java - Input string into array -

i have text file :

testcasez : a, b, c

testcasex : b,d

testcasec : b

i want have string array :

         abcd 

testcasez 1 1 1 0

testcasex 0 1 0 1

testcasec 0 1 0 0

public class teststring {     public static void main(string[] args){          //need configure accordingly                     int row=3+1;         int col=4+1;          string[][] array=new string[row][col];         //construct string number of row-1         string s1="testcasez : a,b,c";         string s2="testcasex : b,d";         string s3="testcasec : b";         string[] strings=new string[]{s1,s2,s3};//strings should have lenghth of row-1         string[] allvalues=new string[]{"a","b","c","d"};          //polulate first row         array[0][1]="a";         array[0][2]="b";         array[0][3]="c";         array[0][4]="d";         //above, can  dynamically construct 2 arrays based on input(say files)          for(int i=1;i<array.length;i++){//for every rest rows             string text=strings[i-1];             string thecase=text.substring(0,text.indexof(":")).trim();//             string valuetext=text.replaceall(thecase, "").replacefirst(":", "").trim();                      array[i][0]=thecase;              string[] values=valuetext.split(",");             list valuelist=arrays.aslist(values);              for(int j=1;j<array[i].length;j++){//for every cols                 if(valuelist.contains(allvalues[j-1])){//if contains value,                      array[i][j]="1";                 }                 else array[i][j]="0";             }         }          //test output                    system.out.println(arrays.deeptostring(array));     } } 

output like:

[[null, a, b, c, d], [testcasez, 1, 1, 1, 0], [testcasex, 0, 1, 0, 1], [testcasec, 0, 1, 0, 0]]
