在多个条件下获取值

function getValueByConditions(condition) {
  if (condition === 'condition1') {
    return 'value1';
  } else if (condition === 'condition2') {
    return 'value2';
  } else if (condition === 'condition3') {
    return 'value3';
  } else {
    return 'default value';
  }
}

console.log(getValueByConditions('condition1')); // 输出：value1
console.log(getValueByConditions('condition2')); // 输出：value2
console.log(getValueByConditions('condition3')); // 输出：value3
console.log(getValueByConditions('condition4')); // 输出：default value

public class GetValueByConditions {
  public static String getValue(String condition) {
    if (condition.equals("condition1")) {
      return "value1";
    } else if (condition.equals("condition2")) {
      return "value2";
    } else if (condition.equals("condition3")) {
      return "value3";
    } else {
      return "default value";
    }
  }

  public static void main(String[] args) {
    System.out.println(getValue("condition1")); // 输出：value1
    System.out.println(getValue("condition2")); // 输出：value2
    System.out.println(getValue("condition3")); // 输出：value3
    System.out.println(getValue("condition4")); // 输出：default value
  }
}
