详解java中if语句和switch的使用

那么
	if(a>b){
    c = 0;
  }else{
    c = 1;
  }

多条件判断
public class Demo {

public static void main(String[] args) {
  int a = 4;
  if(a==1){
    System.out.println("a等于1");
  }else if(a==4){
    System.out.println("a等于4");
  }else if(a==6){
    System.out.println("a等于6");
  }else{
    System.out.println("a不等于1,4,6");
  }
}

比如
public class Demo {

public static void main(String[] args) {
  int a = 6;
  switch (a){
    case 1:
      System.out.println("a等于1");
      break;
    case 4:
      System.out.println("a等于4");
      break;
    case 6:
      System.out.println("a等于6");
      break;
    default:
      System.out.println("a不等于1,4,6");
      break;
  }
}
