Finding the imaginary part of the complex number
String imaginary = s . substring ( i + 1 , l - 1 ) ; int x = Integer . valueOf ( real ) ; int y = Integer . valueOf ( imaginary ) ; if ( x > 0 && y > 0 ) System . out . print ( " Quadrant ▁ 1" ) ; else if ( x < 0 && y > 0 ) System . out . print ( " Quadrant ▁ 2" ) ; else if ( x < 0 && y < 0 ) System . out . print ( " Quadrant ▁ 3" ) ; else if ( x > 0 && y < 0 ) System . out . print ( " Quadrant ▁ 4" ) ; else if ( x == 0 && y > 0 ) System . out . print ( " Lies ▁ on ▁ positive " + " ▁ Imaginary ▁ axis " ) ; else if ( x == 0 && y < 0 ) System . out . print ( " Lies ▁ on ▁ negative " + " ▁ Imaginary ▁ axis " ) ; else if ( y == 0 && x < 0 ) System . out . print ( " Lies ▁ on ▁ negative " + " ▁ X - axis " ) ; else if ( y == 0 && x > 0 ) System . out . print ( " Lies ▁ on ▁ positive " + " ▁ X - axis " ) ; else System . out . print ( " Lies ▁ on ▁ the ▁ Origin " ) ; }
