yeaaaa buddy!!!!!!!!

code:

String examplearray[][] = new String[5][3];

examplearray[0][0] = "hey";

examplearray[0][1] = "1";

examplearray[0][2] = "8";

examplearray[1][0] = "blabla";

examplearray[1][1] = "5";

examplearray[1][2] = "122";

examplearray[2][0] = "meh";

examplearray[2][1] = "3";

examplearray[2][2] = "88";

examplearray[3][0] = "axax";

examplearray[3][1] = "9";

examplearray[3][2] = "88";

examplearray[4][0] = "ababa";

examplearray[4][1] = "9";

examplearray[4][2] = "88";

size(300, 300);

println(int(examplearray[0][0]));

println(int(examplearray[1][0]));

String alfa[]= new String[2];

String alfa2[] = new String[2];

String a[] = new String[examplearray[0].length];

String b[] = new String[examplearray[0].length];

int alfabetisch = 0;

while(alfabetisch<examplearray.length-1)

{

alfa[0]=examplearray[alfabetisch][0];

alfa[1]=examplearray[alfabetisch+1][0];

alfa2[0]=examplearray[alfabetisch][0];

alfa2[1]=examplearray[alfabetisch+1][0];

alfa =sort(alfa);

if (alfa[0] != alfa2[0]) {

a= examplearray[alfabetisch];

b= examplearray[alfabetisch+1];

examplearray[alfabetisch] = b;

examplearray[alfabetisch+1] = a;

alfabetisch=0;

}

else

{

alfabetisch++;

}

}

String x[] = new String[examplearray[0].length];

String z[] = new String[examplearray[0].length];

int checkrow;

for (int kolom=1; kolom<examplearray[0].length; kolom++) {

checkrow = 0;

while (checkrow<examplearray.length-1) {

if (int(examplearray[checkrow][kolom]) < int(examplearray[(checkrow+1)][kolom])) {

x = examplearray[checkrow];

z = examplearray[checkrow+1];

examplearray[checkrow]= z;

examplearray[checkrow+1]=x;

checkrow=0;

}

else

{

checkrow++;

}

}

}

for (int i = 0; i<examplearray.length; i++) {

for (int t=0; t<examplearray[i].length; t++) {

text(examplearray[i][t], 20+60*t, 20+20*i);

}

}

how can I make a random array, that has a random value which occurs only once per array.

int[] randomarray = new int[18];

int check;

for (int i = 0; i<18; i++) {

check=0;

randomarray[i] = int(random(0, 20));

while (check<18) {

if (randomarray[i] == randomarray[check]) {

randomarray[i] = int(random(0, 20));

check=0;

}

else {

check++;

}

}

}

thanks in advance! :)

hey,

I want to calculate with a 2d string, how do I have tot do this??

It have to be a string[][] for me!

String[][] meh = new String[5][8];

for(int i=0; i<meh.length; i++){

meh[i]="1";

}

for(int i=0; i<meh.length; i++){

int(meh[i][1])++;

}
