使用例
object Test {
def main(args: Array[String]) {
var a = 10;
var b = 20;
var c = 25;
var d = 25;
println("a + b = " + (a + b) );
println("a - b = " + (a - b) );
println("a * b = " + (a * b) );
println("b / a = " + (b / a) );
println("b % a = " + (b % a) );
println("c % a = " + (c % a) );
}
}
object Test {
def main(args: Array[String]) {
var a = 10;
var b = 20;
var c = 25;
var d = 25;
println("a + b = " + (a + b) );
println("a - b = " + (a - b) );
println("a * b = " + (a * b) );
println("b / a = " + (b / a) );
println("b % a = " + (b % a) );
println("c % a = " + (c % a) );
}
}
object Test { def main(args: Array[String]) { var a = 10; var b = 20; var c = 25; var d = 25; println("a + b = " + (a + b) ); println("a - b = " + (a - b) ); println("a * b = " + (a * b) ); println("b / a = " + (b / a) ); println("b % a = " + (b % a) ); println("c % a = " + (c % a) ); } }
実行結果
a + b = 30
a – b = -10
a * b = 200
b / a = 2
b % a = 0
c % a = 5
