Java if简单用法

/**

public class TestJava_f
{public  static void main(String[] args)
{
    int a = 6, b = 5;
    System.out.println("a = "+a+",b = "+b);
    if (a>b)
        System.out.println("a -b = " +(a-b));
    System.out.println("a*b = "+(a*b));
    
}
}

//若是if语句要处理的语句只有要给，可省略左右大括号

结果 a = 6,b = 5 a -b = 1 a*b = 30
