Pythagorean triple calculation in java -

-

i found way calculate pythagorean triple until number,but program duplicates , in different order . how can avoid this? try organize pythagorean triple c value (aa+bb=c*c) code

    import java.util.scanner; public class ex4 {     public static void main(string[] args) {         scanner s = new scanner(system.in);         int number;         number = s.nextint();         for(int c=1;c<number;c++){             for(int b=1;b<number;b++){                 for(int a=1;a<number-2;a++){                     if(a*a + b*b == c*c)                         system.out.println("("+a+","+b+","+c+") : "+a+"*"+a+" + "+b+"*"+b+" = "+c+"*"+c);                 }             }         }     } }

make change:

    for(int c=1;c<number;c++){         for(int b=1;b<c;b++){             for(int a=1;a<b;a++){                 if(a*a + b*b == c*c )

but aware more efficient methods such euclid's formula

-
i'm combining 3d content three.js html , svg content. three.js cssloader pretty job synchronizing placement of html , svg content in 3d world. but svg/html coordinate systems 'left-handed', whereas three.js coordinate system 'right-handed'. means y-axes reversed. in svg/html, y / top goes go down screen, , three.js uses more standard mathematical convention of y going down go down screen. i have continually convert 1 other, pretty error prone. know not first run (for example, look here ). has come general solution? here's tried: do in object3d .scale.y = -1 . may suspect, turns out disaster. turns inside-out, , don't try put camera in there. do in object3d .rotate.x = math.pi . more promising, z axis no longer consistent html concept of z-index. still, i'm using now. in html, don't use top , use bottom . in svg , inside <g transform="scale(1, -1)"> inside <g transform="translate(0, imageheight)"> . h...
